I have a large set of html-pages (css-formatted, + some javascript) that I want saved inside the project so the user dont have to go online to browse for them from the app.
1) My first question is how do I open a a local html-page (named, for instance "myWebPage.html") in a WebView?
I know I can make a WebView load a html-string with the following code:
main.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView android:id="@+id/webkit"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
WebKitTest.java
Code:
package com.androidspanishcourse.WebKitTest;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebKitTest extends Activity {
// Declare webview
WebView browser;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// ?
browser=(WebView)findViewById(R.id.webkit);
// Loads html-string into webview
browser.loadData("<html><body>Hi dude<br><br>Hi again</body></html>", "text/html", "UTF-8");
}
}
But I dont know how to load a specific local html-page.
2) My second question is: where do I put the html-pages? I understand that resources are generally put in the /res/-folder of the project, but do I put them in a specific sub-folder of the res-folder?
http://developer.android.com/reference/android/webkit/WebView.html
1.Webview.loadUrl(String url)
2.The prefix "file:///android_asset/" will cause WebView to load content from the current application's 'assets' folder. For example, a myimage.gif file in the /assets folder can be used in the html image tag as:
<img src="file:///android_asset/myimage.gif">. Same applies to html file.
Thanks a lot, waacow
Also, apparently you need to add "browser.getSettings().setJavaScriptEnabled(true);" for the webview to be able to handle javascript.
Display HTML file from assets folder
Hello,
Just save your HTML file in your assets folder and then load it from assets to webview.
MainActivity.java
package com.deepshikha.htmlfromassets;
import android.app.ProgressDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
WebView webview;
ProgressDialog progressDialog;
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init(){
webview = (WebView)findViewById(R.id.webview);
webview.loadUrl("file:///android_asset/download.html");
webview.requestFocus();
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Loading");
progressDialog.setCancelable(false);
progressDialog.show();
webview.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
try {
progressDialog.dismiss();
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
}
Thanks!
I'm having trouble replacing certain drawables, i've made a few work, some others just don't get replaced.
Here's a bit for a part that works.
Code:
package mjxl.xposed.cm11;
import android.content.res.XModuleResources;
import android.content.res.XResources;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
public class CM11transparentstuff implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
private static String MODULE_PATH = null;
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
MODULE_PATH = startupParam.modulePath;
}
@Override
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
XModuleResources modRes = XModuleResources.createInstance(MODULE_PATH, resparam.res);
resparam.res.setReplacement("android", "drawable", "overscroll_edge", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
return new ColorDrawable(Color.TRANSPARENT);
}
});
}
}
Now i want to replace the notification_bg_normal.9.png and notification_bg_normal_pressed.9.png with my versions.
Technically i should be able to add a line like this:
resparam.res.setReplacement("android", "drawable", "notification_bg_normal", modRes.fwd(R.drawable.not_bg_normal));
And ofcourse add the drawable (notification_bg_normal_BLA.9.png) in my folder (xhdpi in my case)
Then i've tried to do it in a different class like this, which fails aswell. :/
Code:
package mjxl.xposed.cm11;
import android.content.res.XModuleResources;
import android.content.res.XResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
public class CM11notifications implements IXposedHookZygoteInit {
public void initZygote(StartupParam startupParam) throws Throwable {
XModuleResources modRes = XModuleResources.createInstance(startupParam.modulePath, null);
XResources.setSystemWideReplacement("android", "drawable", "notification_bg", modRes.fwd(R.drawable.notification_bg)); <<<<--- notification_bg.xml (doesnt work)
XResources.setSystemWideReplacement("android", "drawable", "notification_bg_normal", modRes.fwd(R.drawable.not_bg_normal)); <<<<---- notification_bg_normal.9.png (also does not work)
XResources.setSystemWideReplacement("android", "drawable", "notification_bg_normal_pressed", modRes.fwd(R.drawable.not_bg_normal_pressed));
}
}
Any help ? What am i missing ?
Just fyi, i don't have any Java programming experience.
I followed the steps on Github wiki, and i've made SOME stuff work.. Why don't these work ?
/added:
I also made this, it's in 'framework-res' aswell, but this one DOES seem to work.
Code:
package mjxl.xposed.cm11;
import android.content.res.XResources;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
public class ts2 implements IXposedHookZygoteInit, IXposedHookInitPackageResources {
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
}
@Override
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
resparam.res.setReplacement("android", "drawable", "overscroll_glow", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
return new ColorDrawable(Color.TRANSPARENT);
}
});
resparam.res.setReplacement("android", "drawable", "overscroll_edge", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
return new ColorDrawable(Color.TRANSPARENT);
}
});
}
}
Trying to hook the layout where the notification_bg.xml is called as background.
Following the "Modifying Layouts" on the Github Tutorial i came up to this:
Code:
package mjxl.xposed.cm11;
import android.widget.TextView;
import de.robv.android.xposed.IXposedHookInitPackageResources;
import de.robv.android.xposed.XposedBridge;
import de.robv.android.xposed.callbacks.XC_InitPackageResources.InitPackageResourcesParam;
import de.robv.android.xposed.callbacks.XC_LayoutInflated;
public class CM11notifications implements IXposedHookInitPackageResources {
public void handleInitPackageResources(InitPackageResourcesParam resparam) throws Throwable {
resparam.res.hookLayout("android", "layout", "notification_template_base", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
TextView notif = (TextView) liparam.view.findViewById(
liparam.res.getIdentifier("status_bar_latest_event_content", "id", "android"));
notif.setBackgroundResource(R.drawable.notification_bg);
XposedBridge.log("hey Ho");
}
});
resparam.res.hookLayout("android", "layout", "notification_template_big_base", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
TextView notif = (TextView) liparam.view.findViewById(
liparam.res.getIdentifier("status_bar_latest_event_content", "id", "android"));
notif.setBackgroundResource(R.drawable.notification_bg);
XposedBridge.log("hey Ho");
}
});
resparam.res.hookLayout("android", "layout", "notification_template_big_text", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
TextView notif = (TextView) liparam.view.findViewById(
liparam.res.getIdentifier("status_bar_latest_event_content", "id", "android"));
notif.setBackgroundResource(R.drawable.notification_bg);
XposedBridge.log("hey Ho");
}
});
resparam.res.hookLayout("android", "layout", "notification_template_inbox", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
TextView notif = (TextView) liparam.view.findViewById(
liparam.res.getIdentifier("status_bar_latest_event_content", "id", "android"));
notif.setBackgroundResource(R.drawable.notification_bg);
XposedBridge.log("hey Ho");
}
});
resparam.res.hookLayout("android", "layout", "notification_template_big_picture", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
TextView notif = (TextView) liparam.view.findViewById(
liparam.res.getIdentifier("status_bar_latest_event_content", "id", "android"));
notif.setBackgroundResource(R.drawable.notification_bg);
XposedBridge.log("hey Ho");
}
});
}
}
Am i making any mistakes here ? i don't see it :/ i've tried setBackground instead of BackgroundResource, but that doesn't get accepted.. Neither does setBackgroundDrawable

How is it not working? Did you check the Xposed log to see if there are any errors there?
Did you verify the drawable you're trying to replace is also on your device (by e.g. decompiling framework-res.apk)? Some vendors remove/rename drawables that are present in AOSP and/or add their own.
I don't get any errors..
The files are there, I decompiled the files myself lol.
Also the log doesn't show either :/
This SHOULD work right?¿
(Added info, I'm working on CM11 sources)
It looks correct to me. Not sure why it wouldn't work. Maybe some of the drawables you're replacing aren't actually used where you think they're used?

I know that i need to address notification_bg.xml, which contains notification_bg_normal(_pressed).9.png (Blurred Sytem-UI by Serajr: clicky, PNG'sclicky)
I just want to replace the drawables. (either xml or the png's)
Another failed try:
Code:
package mjxl.xposed.cm11;
import android.content.res.XResources;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.graphics.drawable.Drawable;
import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.XposedBridge;
public class notBG implements IXposedHookZygoteInit {
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
XposedBridge.log("y0");
XResources.setSystemWideReplacement("android", "drawable", "notification_bg_normal", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
return new ColorDrawable(Color.TRANSPARENT);
}
});
XResources.setSystemWideReplacement("android", "drawable", "notification_bg_normal_pressed", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
return new ColorDrawable(Color.TRANSPARENT);
}
});
}
}
I will has continue.
Also i noticed, i'm replacing 'overscroll_edge' and 'overscroll_glow' (both framework-res package) in handleInitPackageResources while theoretically (according to the tutorials) it should be placed in initZygote
I did some more searching, think i might've found something. I'll keep you guys informed.
//edit: mehhh, im about to give up :/
Are your replacement 9 files 'built'?
PainToad said:

Click to expand...
Click to collapse
What exactly do you mean with 'built' ?
Also, even without the .9 files (by replacing it with a transparent 'newDrawable') it does not work :/

need to get this finished before thursday, so please help me
Well, thus far I see that you are making references to parts of the Layout View but I am not seeing where you are declaring your TextView / ImageView inside your XML layout, see below:
Code:
sw.setImageResource(R.drawable.reclame);
mTextView.setText("Om deze functie te gebruiken moet u NFC aanzetten.");
You need to have something like:
mTextView = (TextView)findViewbyId(R.id.TextViewId);
sw = (ImageView)findViewById(R.id.ImageViewId);
Fix those, try again and then return.
Code:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
protected void onStart(){
super.onStart();
String comments[] = {"Dare 1","Dare 2","Dare 3"};
Random rand = new Random();
int number = rand.nextInt(comments.length);
TextView t = (TextView) findViewById(R.id.msg);
t.setText(comments[number]);
}
public void tf(View view){
Intent myIntent = new Intent(this, TruthFemale.class);
startActivity(myIntent);
}

When i load the app it just crashes...
Found the issue. I didnt name the textview properly and was crashing because of it. Problem resolved...
I'm trying to create a widget that will show the icon's of some app's installed on the device.
I manage to get a list of packages installed in the device, but i don't know how to get the icon from these.
I have this in my activity:
Code:
final static List<String> pacote_app = new ArrayList<String>();
final List<ApplicationInfo> apps = pm.getInstalledApplications(0);
for (ApplicationInfo app : apps) {
//checks for flags; if flagged, check if updated system app
if ((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
// installedApps.add(app);
//it's a system app, not interested
} else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
//Discard this one
//in this case, it should be a user-installed app
} else {
String pacote = (String) app.packageName; //NOME DOS PACOTES
pacote_app.add(pacote);
}
}
// ATTENTION: This was auto-generated to implement the App Indexing API.
// See https://g.co/AppIndexing/AndroidStudio for more information.
client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
WidgetViewsFactory
Code:
import static com.example.magcr23.mywidget.LoremActivity.pacote_app;
public class WidgetViewsFactory implements RemoteViewsService.RemoteViewsFactory {
Context context;
private Context ctxt=null;
private int appWidgetId;
public WidgetViewsFactory(Context ctxt, Intent intent) {
this.ctxt=ctxt;
appWidgetId=intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
}
@Override
public void onCreate() {}
@Override
public void onDestroy() {
// no-op
}
@Override
public int getCount() {
return(pacote_app.size());
}
@Override
public RemoteViews getViewAt(int position) {
RemoteViews row=new RemoteViews(ctxt.getPackageName(),
R.layout.list_item);
//FILL LIST
row.setTextViewText(android.R.id.text1, pacote_app.get(position));
//SEND WORD TO ACTIVITY
Intent i=new Intent();
Bundle extras=new Bundle();
extras.putString(WidgetProvider.EXTRA_WORD, pacote_app.get(position));
i.putExtras(extras);
row.setOnClickFillInIntent(android.R.id.text1, i);
//--------------
return(row);
}
@Override
public RemoteViews getLoadingView() {
return(null);
}
@Override
public int getViewTypeCount() {
return(1);
}
@Override
public long getItemId(int position) {
return(position);
}
@Override
public boolean hasStableIds() {
return(true);
}
@Override
public void onDataSetChanged() {
// no-op
}
}
WidgetProvider
Code:
public class WidgetProvider extends AppWidgetProvider{
public static String EXTRA_WORD=
"com.commonsware.android.appwidget.lorem.WORD";
@Override
public void onUpdate(Context ctxt, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
for (int i=0; i<appWidgetIds.length; i++) {
Intent svcIntent=new Intent(ctxt, WidgetService.class);
svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews widget=new RemoteViews(ctxt.getPackageName(),
R.layout.novo_widget);
widget.setRemoteAdapter(appWidgetIds[i], R.id.listagem,
svcIntent);
Intent clickIntent=new Intent(ctxt, LoremActivity.class);
PendingIntent clickPI=PendingIntent
.getActivity(ctxt, 0,
clickIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
widget.setPendingIntentTemplate(R.id.listagem, clickPI);
appWidgetManager.updateAppWidget(appWidgetIds[i], widget);
}
super.onUpdate(ctxt, appWidgetManager, appWidgetIds);
}
}
WidgetService
Code:
public class WidgetService extends RemoteViewsService {
@Override
public RemoteViewsFactory onGetViewFactory(Intent intent) {
return(new WidgetViewsFactory(this.getApplicationContext(),
intent));
}
Layout
Code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="@dimen/widget_margin"
android:orientation="horizontal">
<ListView
android:id="@+id/listagem"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
ListView Layout
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:minHeight="?android:attr/listPreferredItemHeight"
android:textColor="#000"
/>
</LinearLayout>

Hi,
You should give a look to PackageItemInfo methods, especially loadIcon (https://developer.android.com/refer...ml#loadIcon(android.content.pm.PackageManager)
In your code:
Code:
final static List<String> pacote_app = new ArrayList<String>();
final List<ApplicationInfo> apps = pm.getInstalledApplications(0);
for (ApplicationInfo app : apps) {
//checks for flags; if flagged, check if updated system app
if ((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
// installedApps.add(app);
//it's a system app, not interested
} else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
//Discard this one
//in this case, it should be a user-installed app
} else {
String pacote = (String) app.packageName; //NOME DOS PACOTES
pacote_app.add(pacote);
// I guess you want to get your icon here
Drawable packageIcon = app.loadIcon(pm);
}
}
To show it, the easiest might be to add an ImageView and call setImageDrawable
Good luck!
