From decompiler I got:
package com.myapp.pk1
public class B {
... ...
public interface a<T> {
void onFailed(String str1, String str2)
void onSuccess(T v1);
}
}
package com.myapp.pk2
public class MyCustomClass {
... ...
}
... ...
package com.myapp.pk3
public class C {
... ...
public static void d(boolean var0, B.a<MyCustomClass> var1){
... ...
}
}
package com.myapp.pk3
public class AppClass {
... ...
C.d(v1, new B.a<MyCustomClass>() {
public void a(MyCustomClass v3) {
... ...
}
public void onFailed(String var1, String var2) {
}
}
... ...
}
Here the instance of B.a is the callback of method C.d
How can I reate an instance of that (interface?) with my own method of onSucces and onFailed?
Thnx a lot

I've searched the android website but I cannot find any sample code that will allow you to download something from a webpage/website. I'm trying to create a simple application that will allow you to download a podcast from a website straight onto the phone's sdcard. Any help is appreciated. Thanks!
[Edit]: I've found http://developer.android.com/reference/android/webkit/DownloadListener.html it seems right but I'm still a beginner and not sure how to apply the code / modify it and where to place it.
Networking is a big series of tests. Just about everything needs to be within a try/catch block, and you need to think of and test every possible contingency. Without doing that, you WILL get crashes and ugliness.
It is not the simplest thing for a newb to implement.
The SECOND thing you need to note is that WEBKIT is not what you want to mess with for *pure downloads*. If you just want to pull a file and do something manual with it, you do NOT want to be messing with an html rendering engine (that's what webkit is...).
Third, network requests should be done in a SEPARATE THREAD from the UI, otherwise it will result in a terrible user experience, ANR's, and general appearance of FREEZUPS.
You can try some of this:
Code:
public class HTTPGetData {
private byte[] data;
public HTTPGetData(){
}
public byte[] toByteArray(){
return data;
}
public void getViaHttpConnection(String url) throws IOException{
HttpClient httpClient = new DefaultHttpClient();
Log.d("***HTTPGetData",url);
HttpGet request = new HttpGet(url);
request.addHeader("Accept-Encoding", "gzip");
HttpResponse response;
try {
response = httpClient.execute(request);
boolean gzip = false;
if (response.containsHeader("Content-Encoding")){
Header[] headers = response.getHeaders("Content-Encoding");
for (int i=0; i<headers.length; i++){
if (headers[i].getValue().compareToIgnoreCase("gzip")==0) gzip = true;
}
}
int status = response.getStatusLine().getStatusCode();
// we assume that the response body contains the error message
if (status != HttpStatus.SC_OK) {
ByteArrayOutputStream ostream = new ByteArrayOutputStream();
response.getEntity().writeTo(ostream);
Log.e("HTTP_CLIENT", ostream.toString());
throw new IOException("HTTP response code: " + status);
} else {
int len = (int)response.getEntity().getContentLength();
InputStream content;
if (gzip) content = new GZIPInputStream(response.getEntity().getContent());
else content = response.getEntity().getContent();
if (len>0 && !gzip){
byte[] theData = new byte[len];
int rec = 0;
int cread = 0;
boolean fail=false;
while (rec < len){
if ((cread=content.read(theData, rec, len-rec))==0){
Log.e("HTTP_CLIENT","Short");
fail=true;
break;
}
rec+=cread;
}
if (!fail) data=theData;
} else {
int ch;
ByteVector bv = new ByteVector(1000);
while ((ch = content.read()) != -1){
bv.add((byte)ch);
}
data = bv.toByteArray();
}
content.close(); // this will also close the connection
}
} catch (ClientProtocolException e) {
Log.e("HTTP_CLIENT","ClientProtocolException");
throw new IOException("ClientProtocolException caught in HTTPGetData.getViaHttpConnection(String url)");
} catch (IOException e) {
Log.e("HTTP_CLIENT","IOException");
throw new IOException("IOException caught in HTTPGetData.getViaHttpConnection(String url)");
}
}
}
What you can do with that is something like this;
try{
HTTPGetData hgd = new HTTPGetData();
hgd.getViaHttpConnection("http://someurl");
//open file and dump in hgd.toByteArray();
catch(IOException e){
//do something with e
}
... and of course, put that in some new thread and while its running, make something spin to give the user the impression of progress.
Thanks lb. I don't really understand perfectly but I will look up the stuff I do not understand. Thanks for the help
I am trying to hook this method, I want to filter out the "Google Play services" from there...(is under settings app)
Code:
/**
* Fills a list of applications which queried location recently within
* specified time.
*/
public List<Preference> getAppList() {
// Retrieve a location usage list from AppOps
AppOpsManager aoManager =
(AppOpsManager) mActivity.getSystemService(Context.APP_OPS_SERVICE);
List<AppOpsManager.PackageOps> appOps = aoManager.getPackagesForOps(
new int[] {
AppOpsManager.OP_MONITOR_LOCATION,
AppOpsManager.OP_MONITOR_HIGH_POWER_LOCATION,
});
// Process the AppOps list and generate a preference list.
ArrayList<Preference> prefs = new ArrayList<Preference>();
long now = System.currentTimeMillis();
for (AppOpsManager.PackageOps ops : appOps) {
// Don't show the Android System in the list - it's not actionable for the user.
// Also don't show apps belonging to background users.
int uid = ops.getUid();
boolean isAndroidOs = (uid == Process.SYSTEM_UID)
&& ANDROID_SYSTEM_PACKAGE_NAME.equals(ops.getPackageName());
if (!isAndroidOs && ActivityManager.getCurrentUser() == UserHandle.getUserId(uid)) {
Preference pref = getPreferenceFromOps(now, ops);
if (pref != null) {
prefs.add(pref);
}
}
}
return prefs;
}
I can't hook this method, I'v tried something like :
Code:
if (lpparam.packageName.equals("com.android.settings")) {
findAndHookMethod("com.android.settings.location.LocationSettings", lpparam.classLoader, "getAppList", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedBridge.log("Called");
}
what is the best approach to achieve this?

Why not? Are there any errors in the Xposed log?
If not, I'd make sure the package name is correct and that the method is actually called when you expect it to be.
Code:
09-29 11:06:53.600 5277 5277 I Xposed : java.lang.NoSuchMethodError: com.android.settings.location.RecentLocationApps#getAppList(java.util.List)#exact
running on Samsumg Note 3.

That error doesn't correspond to the code you've posted in the first post. Post the modified code and the error.
Purely guessing, though: Samsung modified the code you're trying to hook. You're hooking the methods you're seeing in the AOSP code, but that's not the case on your device.
You are correct, sorry. I'm trying a lot of different stuff.
this is the code:
Code:
try
{
findAndHookMethod("com.android.settings.location.RecentLocationApps", lpparam.classLoader,
"getAppList", List.class, new XC_MethodHook() {
@SuppressWarnings("unchecked")
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable
{
XposedBridge.log("RecentLocationApps.getAppList()");
}
});
}
catch(Throwable t)
{
XposedBridge.log(t);
}
the throwable is :
Code:
09-29 11:56:08.559 5282 5282 I Xposed : java.lang.NoSuchMethodError: com.android.settings.location.RecentLocationApps#getAppList(java.util.List)#exact
if tried to do that for every package, not just com.android.settings or com.android.settings.location and it doesn't seem to work.
do you know what's the correct package? do I have to start dedexing Samsung's packages to get the answer?

com.android.settings should be the correct package, if I'm not mistaken.

That'd be the best thing to do as it looks like Samsung has changed some things.
Hello world,
Question: What's the code line(S) to select an image from gallery? Thank you in advance.
Code:
private void openPictureChooser() {
PackageManager manager = getPackageManager();
String memoryState = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(memoryState)) {
Intent mIntent = new Intent(Intent.ACTION_PICK);
mIntent.setType("image/*");
List list = manager.queryIntentActivities(mIntent, PackageManager.MATCH_DEFAULT_ONLY);
if (!list.isEmpty()) {
startActivityForResult(mIntent, REQUEST_CODE);
}
} else {
Toast.makeText(this, getString(R.string.your_message), Toast.LENGTH_LONG).show();
}
}
Volley is an HTTP library that makes networking for Android apps easier and faster.
We need to set the context before sending requests, according to nameless-technology.blogspot.com /2013/11/custom-system-service-using-xposedbridge.html, my testing code was:
Code:
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
...
protected void beforeHookedMethod(MethodHookParam param) throws
Throwable {
...
Context context = (Context) param.getResult();
RequestQueue queue = Volley.newRequestQueue(context);
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
msgs_g = response;
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
msgs_g = "That didn't work!";
}
});
queue.add(stringRequest);
However, when the module was loading, there's an exception:
Code:
java.lang.NullPointerException
at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:45)
at com.android.volley.toolbox.Volley.newRequestQueue(Volley.java:105)

at de.robv.android.xposed.XposedBridge.handleHookedMethod(XposedBridge.java:611)
From code you provided it's not clear what method exactly you are hooking. But some remarks, anyway:
- are you sure original method returns context?
- I'm not sure whether using getResult() in before hook is a good practice, as you are basically asking for a return value when method was not executed, yet.
You should try after hook instead

@C3C076 Thanks for your reply.
I just modified the code from `beforeHookedMethod` to `afterHookedMethod`, at this time, I got nothing in my log.
What I want to hook is the function `dispatchSensorEvent` in the `android.hardware.SystemSensorManager$SensorEventQueue` class. Actually I don't whether this method returns context, thanks for reminding me.
Finally I used `AsyncTask` with `DefaultHttpClient` to get the data from the web site, I still use `beforeHookedMethod`.

How to start alarm when activity start which also contains message and stop button
Alarm or alert?
If you need alert take this code .
Code:
new AlertDialog.Builder(context)
.setTitle("Delete entry")
.setMessage("Are you sure you want to delete this entry?")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// continue with delete
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// do nothing
}
})
.setIcon(android.R.drawable.ic_dialog_alert)
Bye
