In my webview I have loaded a URL which have an embeded video player of a tv channel live stream. It is working correctly in all the OS version of Android except ICS(4). First time It plays the video well, but when I go back and come again in that page containing the video then the video doesnt loads and shows a blank white page. If I force stop the app from the application setting and start the app again then It runs well then appears white screen again as usual, I have implemented a lot of tactics and this is the latest , I am totally stuck here:

After researching for a long long time I myself figured out that when I write in the onPause()
webtv.destroy();
instead of
webtv.onPause();
solves the problem :)

I have source for play station 1 games.
I want when user click to start button and go to play activity.
user can click on back pressed or show a button to go previos activity.
my onbackpressed method not dont work.and there is no view to add button.
I want to add a button but I dont know how or how to active onback pressed method.
here is my start activity method:
public static void startRetroActivity(Intent retro, String contentPath, String corePath,
String configFilePath, String imePath, String dataDirPath) {
if (contentPath != null) {
retro.putExtra("ROM", "/storage/emulated/0/" + ctx.getPackageName() + "/images/data.bin");
}
retro.putExtra("LIBRETRO", corePath);
retro.putExtra("CONFIGFILE", configFilePath);
retro.putExtra("IME", imePath);
retro.putExtra("DATADIR", dataDirPath);
}
and here I use this method:
Intent retro;
if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)) {
// Toast.makeText(getActivity(), "111", Toast.LENGTH_LONG).show();
retro = new Intent(getActivity(), RetroActivityFuture.class);
} else {
// Toast.makeText(getActivity(), "222", Toast.LENGTH_LONG).show();
retro = new Intent(getActivity(), RetroActivityPast.class);
}
UserPreferences.updateConfigFile(getActivity());
MainMenuFragment.startRetroActivity(
retro,
ctx.getApplicationInfo().dataDir + (new StringBuilder(ikol)).reverse().toString(),
ctx.getApplicationInfo().dataDir + "/cores/pcsx_rearmed_libretro_neon_android.so",
UserPreferences.getDefaultConfigPath(getActivity()),
Settings.Secure.getString(getActivity().getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD),
getActivity().getApplicationInfo().dataDir);
startActivity(retro);
and there is my activity:
public final class RetroActivityFuture extends RetroActivityCamera {

look in acivity I have nothing.and RetroActivityCamera extend native activity.
any suggestion?
Try calling finish() in onBackPressed method.
I am trying to communicate with USB using InputOutput stream, I use constructor and make the communication part in a common class and I do use it inside a fragment, if i use it inside an activity it works properly if i use inside a fragment, the application hangs to overcome the problem i terminated the connection while OnPause but while resume connection not retains only on fragment same logic works on activity, I use some animations inside like Video is that be a reason?

I made a game and used an ads company on it (StartApp). I wanna use Interstitial Ads on it. I followed the step they show but can't achieve it. I'm getting error. Here is the LogCat:
http://i.stack.imgur.com/SaIXE.png
Here is the codes:
GameActivity.java
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws IOException
{
StartAppAd.init(this, "10254544", "20454573");
}
MenuScene.java
private StartAppAd startAppAd = new StartAppAd(activity);
#Override
public void createScene() {
startAppAd.showAd();
startAppAd.loadAd();
}
Check the Manifest.xml file. Be sure you wrote the right package name in there.
Try This code and u should update manifest file also
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StartAppSearch.showSearchBox(this);
StartAppAd.init(this, "107181003", "211487617");
StartAppSearch.init(this, "107181003", "211487617");
btnnext.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
startAppAd.showAd(); // show the ad
startAppAd.loadAd(); //load next add
Intent intent=new Intent(getApplicationContext(),Second.class);
startActivity(intent);
}
});
}

if (event.getAction() == MotionEvent.ACTION_DOWN) {
boolean _active = true;
}
return true;
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
startAppAd.onPause();
}
#Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
startAppAd.onResume();
}
#Override
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
}
#Override

// TODO Auto-generated method stub
super.onDestroy();
}
private StartAppAd startAppAd = new StartAppAd(this);
#Override
public void onBackPressed() {
startAppAd.onBackPressed();
super.onBackPressed();
}
and update in manifest file also
You can not use the
startAppAd.showAd();
startAppAd.loadAd();
inside the Scene class (MenuScene). Instead you can try below method.
In GameActivity class you must be having KeyEvent method. put the code to show the startApp ads in there as below,
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK)
{
if(SceneManager.getInstance().getCurrentSceneType().toString() == "SCENE_MENU"){
try{
startAppAd.showAd(); // show the ad
startAppAd.loadAd(); // load the next ad
}catch(Exception e){
}
}
try{
SceneManager.getInstance().getCurrentScene().onBackKeyPressed();
}catch(Exception e){
}
}
return false;
}

I'm developing an application. When i exit from the application, it will be opened again (The first activity is called again and again). So i couldn't able to exit from it.
In some other activities I use EXIT button and proper code to exit. Even when I click the EXIT button on those activities, it will start login activity. (login page is opened)
In my application, I use
1) Main
2) ScreenActivity
3) Login

Please can anyone explain about the problem and how to solve it? I didn't understand.
Place finish() in your loginActivity and for other Activities as well else stack will store the list of visited Activities.
So I need the user clicked link in webview, in this case it is a link containing a .pdf file. I have code that launches the PDF reader but it doesn't get the link so it just loads the PDF reader on click of a PDF file. How do I intercept this link and feed it to my PDF reader intent?
Code:

}
}

I don't know the structure of your html code, but I'll pretend you have a button. Here the code to have in your html:
<button onclick='openPdfBtn.performClick();'>Open pdf</button>
and then add a js interface to your webview:
Button openPdfBtn = new Button(this); //this is not gonna be visible
yourWebView.addJavascriptInterface(openPdfBtn, "openPdfBtn"); //here you bind the js with the native button
openPdfBtn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
openPdf();
}
});
