[Q] writing txt file

I want to write a text file. But I am not sure how writing down works in Android. Here is my code:
Code:
EditText textbox1 = (EditText) findViewById(R.id.editText);
EditText textbox2 = (EditText) findViewById(R.id.editText2);
EditText textbox3 = (EditText) findViewById(R.id.editText3);
public void writeToPhonebook(View v) {
Button button=(Button) v;
try {
File fajl = new File("phonebook.txt");
Writer writer;
writer= new BufferedWriter(new OutputStreamWriter(new FileOutputStream(fajl, true), "UTF-8"));
writer.append(textbox1.getText() + "\t" + textbox2.getText() + "\t" + textbox3.getText());
writer.write("\r\n");
writer.close();
textbox1.setText("");
textbox2.setText("");
textbox3.setText("");
textbox1.requestFocus();
}
catch (IOException ex) {
Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);
ex.printStackTrace();
}
}
can I just leave phonebook.txt or need to put something else? Because with this code apk can't even start on emulator.

OK I done this previus. I now need to load data from text file into table (table layout with 3 columns). Is it possible for application to determine number of needed rows without me adding certain number. Because that data will be changed.

You need permissions to write a file, you set them in the AndroidManifest xml (Every Android Studio project has their own manifest, set it in your project)
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Then you need to open a file for input/output... You do this in whatever.java
Code:
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import android.util.Log;
public class FileOperations {
public FileOperations() {
}
public Boolean write(String fname, String fcontent){
try {
String fpath = "/sdcard/"+fname+".txt";
File file = new File(fpath);
// If file does not exists, then create it
if (!file.exists()) {
file.createNewFile();
}
FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(fcontent);
bw.close();
Log.d("Suceess","Sucess");
return true;
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
public String read(String fname){
BufferedReader br = null;
String response = null;
try {
StringBuffer output = new StringBuffer();
String fpath = "/sdcard/"+fname+".txt";
br = new BufferedReader(new FileReader(fpath));
String line = "";
while ((line = br.readLine()) != null) {
output.append(line +"n");
}
response = output.toString();
} catch (IOException e) {
e.printStackTrace();
return null;
}
return response;
}
}

What is easier to display data from text file in: TableLayout or ViewList? If not sure total number of rows? Is there something for scrooling through it if can't fit the screen?

Scrollview

1) Yes. Android provide scrollview to scroll on your query.
A. Horizontal scrollview
B. Vertical Scrollview.
Also you can you onTextwatcher() to check if the field size increase , onAfterTextchanged() method you can resize the box is.
private final TextWatcher passwordWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
textView.setVisibility(View.VISIBLE);
}
public void afterTextChanged(Editable s) {
if (s.length() == 0) {
textView.setVisibility(View.GONE);
} else{
textView.setText("You have entered : " + passwordEditText.getText());
}
}
};

I found this tutorial for multicolumn ListView on techlovejump.com ,but data for it is hardcoded. I am not sure is it suitable for dynamic data adding from text file.

hey, As you see on after afterTextChanged(Editable s)
You can again call your table structure code to design it as per size.
I think you should try it once.
Share some amount of code if you find it difficult. I will help you afterTextChanged(Editable s).

I don't need to write text but to read it. Can you look at this code and tell me what is the problem? It can't find the file.
Code:
void showData(){
File fajl = new File("phonebook.txt");
try {
BufferedReader br = new BufferedReader(new FileReader(fajl));
String line;
try {
while ((line = br.readLine()) != null) {
TableRow tr = new TableRow(this);
tr.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT));
TextView im = new TextView(this);
im.setText(line);
im.setTextColor(Color.BLACK);
im.setLayoutParams(new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT));
tr.addView(im);
tablel.addView(tr, new TableLayout.LayoutParams(
RelativeLayout.LayoutParams.FILL_PARENT,
RelativeLayout.LayoutParams.WRAP_CONTENT));
}
} catch (IOException e) {
e.printStackTrace();
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
button2.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
showData();
}
});
I have added to xml TableLayout and one row as header.
I use this for writing to text file:
Code:
button.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
try {
FileOutputStream fos = openFileOutput("phonebook.txt", Context.MODE_WORLD_READABLE);
OutputStreamWriter osw = new OutputStreamWriter(fos);
osw.append(textbox1.getText().toString() + "\t" + textbox2.getText().toString() + "\t" + textbox3.getText().toString());
osw.write("\r\n");
osw.close();
textbox1.setText("");
textbox2.setText("");
textbox3.setText("");
textbox1.requestFocus();
} catch (IOException ex) {
Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);
ex.printStackTrace();
}
}
});
Debbuger says it's writting file and lines just fine. But why I can't read it?

It creates "files" folder inside my app folder. And inside files it is phonebook.txt.

PHP, database, SQL app

hi.
i make login and register app' that use php,SQL and database, all work excellent,

WebApp + sql. Can't make sql to work.

Hey guys.
So, I've spent the last two days watching every tutorial about working with sqlite, but I'm doing something wrong and can't find out what.
The app is done, only needs the SQLite part, Its basicly a webapp with favorites.
Altough I have changed the code several times, this is what I ended up with:
DBManager.java
<code>
package com.rjpf.mywebapps;
import android.content.ContentValues;
import android.content.Context;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
public class DBManager
{
private DbHelper dbHelper;
private Context context;
private SQLiteDatabase database;
public DBManager(Context c)
{
context=c;
}
public DBManager open() throws SQLException
{
dbHelper = new DbHelper(context);
database = dbHelper.getWritableDatabase();
return this;
}
public void close()
{
dbHelper.close();
}
public void insert(String name, String url)
{
ContentValues contentValue = new ContentValues();
contentValue.put(DbHelper.CONTACTS_COLUMN_NAME, name);
contentValue.put(DbHelper.CONTACTS_COLUMN_URL, url);
database.insert(dbHelper.CONTACTS_TABLE_NAME, null, contentValue);
}
}
</code>
When I try to call it in the main activity with:
MainActivity.java
<code>
(...)
private LinearLayout Layout_Add;
private TextView TxT_add_nomE;
private TextView TxT_add_urL;
private Button Button_Add_to_DB;
private Button btn_BACK_Add;
DbHelper myDB;
(...)
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myDB = new DbHelper(this);
(...)
Button_Add_to_DB.setOnClickListener(new View.OnClickListener() {
@override
public void onClick(View view) {
Add_ItemToDb();
}
});
(...)
public void Add_ItemToDb()
{
if (TxT_add_nomE.getText().toString().trim().length() == 0 || TxT_add_urL.getText().toString().trim().length() == 0)
{
TxT_add_nomE.setText("Please don't leave fields empty!");
return;
}
else
{
String addNome = TxT_add_nomE.getText().toString();
String addUrl = TxT_add_urL.getText().toString();
// ADD TO DB
DBManager DataManager = new DBManager(this);
DataManager.insert(addNome,addUrl); // This line is what gives the error, when I click the button to add the App craches
TxT_add_nomE.setText("Name");
TxT_add_urL.setText("Url");
}
}
</code>
Thanks in advance and sorry for the long post, This is my first app and also the first time in java

Android Don't execute anything until location variable exists

Goodmorning, I've tried to implement the method that request permission first and than execute something but without success ...
Here is my MainActivity code:
Code:
public class MainActivity extends AppCompatActivity {
public static String latitudineCorrente = ""; //current Latitude
public static String longitudineCorrente = ""; //current Longitude
private SharedPreferences sharedPreferences; //shared preferences
private SharedPreferences.Editor mEditor; // shared preferences editor
/* Variable for getting location */
private FusedLocationProviderClient fusedLocationProviderClient;
private LocationRequest locationRequest;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String appLanguage = "ita";
LanguageUtil.setAppLanguage(getApplicationContext(), appLanguage);
/* .... other code.... */
sharedPreferences = this.getSharedPreferences("appname", MODE_PRIVATE);
mEditor = sharedPreferences.edit(); // set edit sharedpreferences
richiamaPermessi(); //permission request
requestLocationUpdates(); // function requestlocationupdates();
CaricamentoInizialeApplicazione(); // function for presetting configurations
}
private void CaricamentoInizialeApplicazione() {
boolean configIniziale = sharedPreferences.getBoolean("configurazioneinizialeok", false);
if(!configIniziale)

0, 0,0,1, 0,0,
new Response.Listener<String>() {
@Override

});
}
}
The problem is executing function ApiMarkers.getMarkers(.... with latitude and longitude filled ...) but can't execute because latitude and longitude are not loaded... I spent two nights without solution Thanks for any help! Cristian

Up! I tried to follow this video on youtube youtube.com/watch?v=gEcFf2Mv4L0 and in any case I could not understand where or when I can call the method "CaricamentoInizialeApplicazione ()" in order to call a method that uses the location coordinates! What I want is to make sure that I don't call the method already said until the location coordinates are loaded into the variables indicated in the code! Is it possible that someone is not able to solve the problem? Thank you

Oh thanks for any help!

[Xposed][For Devs] How to dynamically declare permissions for a target app without altering its manifest and changing its signature

Have you ever tried to extend your favorite app with new features using Xposed, but were shocked halfway that your hooked app doesn't declare a permission in AndroidManifest ? And then you spent infinite hours on the internet trying to solve this frustrating problem, you decided to use services and an external intent, but you found out that it was not convenient, and finally you gave up...
So you are like me, who wasted hours looking for a solution, until I figured out how to do it myself. Here's a snippet to save time for future Xposed enthusiasts. Put this code snippet in handleLoadPackage
Java:
// Hook will only patch System Framework
if (!lpparam.packageName.equals("android")) return;
String targetPkgName = "com.example.app"; // Replace this with the target app package name
String[] newPermissions = new String[] { // Put the new permissions here
"android.permission.INTERNET",
"android.permission.ACCESS_NETWORK_STATE"
};
String grantPermissionsMethod = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
grantPermissionsMethod = "restorePermissionState";
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.S_V2) {
XposedBridge.log("[WARNING] THIS HOOK IS NOT GUARANTEED TO WORK ON ANDROID VERSIONS NEWER THAN ANDROID 12");
}
} else if (Build.VERSION.SDK_INT == Build.VERSION_CODES.P) {
grantPermissionsMethod = "grantPermissions";
}
else {
grantPermissionsMethod = "grantPermissionsLPw";
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN) {
XposedBridge.log("[WARNING] THIS HOOK IS NOT GUARANTEED TO WORK ON ANDROID VERSIONS PRIOR TO JELLYBEAN");
}
}
XposedBridge.hookAllMethods(XposedHelpers.findClass("com.android.server.pm.permission.PermissionManagerService", lpparam.classLoader),
grantPermissionsMethod, new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
// on Android R and above, param.args[0] is an instance of android.content.pm.parsing.ParsingPackageImpl
// on Android Q and older, param.args[0] is an instance of android.content.pm.PackageParser$Package
// However, they both declare the same fields we need, so no need to check for class type
String pkgName = (String) XposedHelpers.getObjectField(param.args[0], "packageName");
XposedBridge.log("Package " + pkgName + " is requesting permissions");
if (pkgName.equals(targetPkgName)) {
List<String> permissions = (List<String>) XposedHelpers.getObjectField(param.args[0], "requestedPermissions");
for (String newPermission: newPermissions) {
if (!permissions.contains(newPermission)) {
permissions.add(newPermission);
XposedBridge.log("Added " + newPermission + " permission to " + pkgName);
}
}
}
}
});
Notes:
You must check System Framework in LSposed Manager
A reboot is required after adding the target permissions
You still need to prompt the user to accept sensitive permissions (ie android.permission.READ_CONTACTS), even if you have added them using this method

Wow, thx. Great for the install permissions!
I wrote a class to grant install and runtime/sensitive permissions (without prompting users).
Android 12 and 13 implementation:
Java:
public class Grant_Package_Permissions {
private static final int sdk = android.os.Build.VERSION.SDK_INT;

Class<?> AndroidPackage = XposedHelpers.findClass(
"com.android.server.pm.parsing.pkg.AndroidPackage", lpparam.classLoader);
Class<?> PermissionCallback = XposedHelpers.findClass(
sdk >= 33 /* android 13+ */ ?
"com.android.server.pm.permission.PermissionManagerServiceImpl$PermissionCallback" :

XposedHelpers.findAndHookMethod(PermissionManagerService, "restorePermissionState",

for (int userId : userIds) {
List<String> requestedPermissions;
Object userState = XposedHelpers.callMethod(mState, "getOrCreateUserState", userId);

grantInstallOrRuntimePermission(requestedPermissions, uidState, mRegistry,
Manifest.permission.READ_CONTACTS);
}
}
}
});
} catch (Exception e) {
XposedBridge.log(e);
}
}
private static void grantInstallOrRuntimePermission(List<String> requestedPermissions, Object uidState,
Object registry, String permission) {
if (!requestedPermissions.contains(permission))
XposedHelpers.callMethod(uidState, "grantPermission",
XposedHelpers.callMethod(registry, "getPermission", permission));
}
}
Edit: Android 12 and 13 implementation!

this looks promising. how to use this in xposed ? is there a module available?
