Google billing API automatically refunding in-app purchases even after being aknowledged

I tried looking at previous questions and answers but with no luck finding a real solution. I'm acknowledging purchases once they are processed although my users are still automatically refunded. Below is my whole purchase activity. It's a simple activity with a big button to purchase the app's full version. Anoter button to restore previous purchases. A third button to show some advice if users were not able to restore their purchase.
Any help would be appreciated!

I want to proceed to next action after scanning QR Code? Where should I add Intent?

I need to implement a QR Code scanner on an android project. I implemented the QR Code, however, I do not know how to switch to another action after QR is read.
I want to create an Intent to move to new action but I do not know where to add it.
I need the app to switch to another action as soon as it detects and reads QR Code.
code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scan_test);
CodeScannerView scannerViewTest = findViewById(R.id.scanner_view_test);
codeScannerTest = new CodeScanner(this, scannerViewTest);
askPermission();
if(CameraPermission) {
scannerViewTest.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
codeScannerTest.startPreview();
}
});
codeScannerTest.setDecodeCallback(new DecodeCallback() {
#Override
public void onDecoded(#NonNull Result result) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(ScanTest.this, result.getText(), Toast.LENGTH_SHORT).show();
}
});
}
});
}
}
private void askPermission(){
if(Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP){
if(ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(ScanTest.this, new String[]{Manifest.permission.CAMERA}, CAMERA_PERM);
}else {
codeScannerTest.startPreview();
CameraPermission = true;
}
}
}
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions, #NonNull int[] grantResults) {
if(requestCode == CAMERA_PERM){
if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED){
codeScannerTest.startPreview();
CameraPermission = true;
}else{
if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)){
new AlertDialog.Builder(this)
.setTitle("Permission")
.setMessage("Please provide the camera permission for using all the features of the app")
.setPositiveButton("Proceed", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
ActivityCompat.requestPermissions(ScanTest.this, new String[]{ Manifest.permission.CAMERA}, CAMERA_PERM);
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}).create().show();
} else {
new AlertDialog.Builder(this)
.setTitle("Permission")
.setMessage("You have denied some permissions. Allow all permissions at [Settings] > [Permissions]")
.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Intent settings_intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.fromParts("package", getPackageName(), null));
settings_intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(settings_intent);
finish();
}
}).setNegativeButton("No, Exit app", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
finish();
}
}).create().show();
}
}
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
#Override
protected void onPause() {
if(CameraPermission){
codeScannerTest.releaseResources();
}
super.onPause();
}

You need to add it at the onDecoded method
codeScannerTest.setDecodeCallback(new DecodeCallback() {
#Override
public void onDecoded(#NonNull Result result) {
runOnUiThread(new Runnable() {
#Override
public void run() {
Intent intent = Intent(this, YouNextActivity.class);
intent.putExtra("barcode", result.getText());
startActivity(intent);
//Toast.makeText(ScanTest.this, result.getText(), Toast.LENGTH_SHORT).show();
}
});
}
});
You can use the Intent.getExtra("barcode") and can get the value in your next Activity.

The SMS Code is expired. How to get pass this exception been stuck on this for days

I keep on getting the error of sms code has been expiraed please resend it even though it just came in my phone. This for android studio firebase authentication by phone number by the way. Can we solve this error?
Below are the codes:

}
}
The mCallBacks Code:

verifyCode(getVerificationId(),code);
}
}
#Override

}
};
The Verify Code:

How to clear app cache on exit pressed button?

I just want to clear app cache on exit when pressed, tried many answers out there but got errors and didn't work, so here is my code:
if (Config.ENABLE_EXIT_DIALOG) {
AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle(R.string.app_name);
dialog.setMessage(R.string.dialog_close_msg);
dialog.setPositiveButton(R.string.dialog_option_yes, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
MainActivity.this.finish();
}
});
dialog.setNegativeButton(R.string.dialog_option_rate_us, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
final String appName = getPackageName();
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appName)));
} catch (android.content.ActivityNotFoundException anfe) {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appName)));
}
MainActivity.this.finish();

}
});
dialog.show();
} else {
super.onBackPressed();
}

got solved, i think it's old way but it's working fine found it here
i actually used his question code at the end of the my mainActivity file and it worked like a charm, though i guess it's an old way but it's ok.
and here is the code
#Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
clearApplicationData();
}
public void clearApplicationData() {
File cache = getCacheDir();
File appDir = new File(cache.getParent());
if (appDir.exists()) {
String[] children = appDir.list();
for (String s : children) {
if (!s.equals("lib")) {
deleteDir(new File(appDir, s));
Log.i("EEEEEERRRRRRROOOOOOORRRR", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************");
}
}
}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
}
return dir.delete();
}
