There is a video activity, I need to handle:
1) when the first time enter the activity, get the position from intent and play the video
2) keep the same position after rotate
Here is the code to handle first requirement
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.video_full_screen);
ButterKnife.bind(this);
if (getIntent() != null) {
video_url = getIntent().getStringExtra("video_url");
pos = (int)getIntent().getLongExtra("time", 0);
}
player.setOnPreparedListener(this);
player.setVideoURI(Uri.parse(video_url));
}
#Override
public void onPrepared(MediaPlayer mp) {
player.seekTo(pos);
player.start();
}
Here is the code to handle second requirement
#Override
protected void onSaveInstanceState(Bundle outState)
{
outState.putInt("time", (int)player.getCurrentPosition());
player.pause();
super.onSaveInstanceState(outState);
}
#Override
protected void onRestoreInstanceState(Bundle savedInstanceState)
{
int last_pos = savedInstanceState.getInt("time");
player.seekTo(last_pos);
player.start();
super.onRestoreInstanceState(savedInstanceState);
}
The problem is the handling is conflict to each other.
If first time enter progess is 10s , when I play at e.g. 30s and rotate , it still go to 10s instead of 30s.
It is caused by the seekTo(pos) at the onPrepared function but I can not remove that as it handle the first requirement.
How to fix that? Thanks for helping.
Rotating the screen calls onDestroy(). Are you saving the time progress in onDestroy()? For more info on android life cycle see: https://androidcookbook.com/Recipe.seam?recipeId=2636

YouTube player has been released when devices rotate and activity recreated. Then play video. Shows YouTube player has released. I don't know where it released. I have already set it to Null onDestroy Method.
`mPlayer.loadVideo(videoId);`
//pointing YouTube Player released
My solution is to save the current playing time by YouTubePlayer getCurrentTimeMillis() in onSaveInstanceState(Bundle state) when screen rotation gets triggered, and get the time back from onRestoreInstanceState(Bundle state).
Sample code would be:
static final String CURRENT_PLAY_TIME = "current_play_time";
int current_time;
#Override
protected void onSaveInstanceState(Bundle state) {
super.onSaveInstanceState(state);
state.putInt(CURRENT_PLAY_TIME, youTubePlayer.getCurrentTimeMillis());
}
#Override
protected void onRestoreInstanceState(Bundle state) {
super.onRestoreInstanceState(state);
current_time = state.getInt(CURRENT_PLAY_TIME);
}
And after restoring the current playing time let YouTubePlayer load video with it.
youTubePlayer.loadVideo(VIDEO_ID, current_time);
Hope it helps!
A posible solution is make your app vertical or horizontal permanent
For doing this write within your manifest:
<android:screenOrientation="portrait"> //vertical
<android:screenOrientation="landscape"> //horizontal
I have found my Excelent solution..all going good with youtube player
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
if (mPlayer != null)
//Set YouTube Player here;
}
if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
if (mPlayer != null)
//Set YouTube Player here;
}
}
I want to start camera and also to automatically start recording just by clicking an app in android. I have the code to start the camera but I do not know how to start auto capture of the video. Please help.
the code I have for launching camera-
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_c1_main);
Intent intent = new Intent("android.media.action.VIDEO_CAPTURE");
StartActivityForResult(intent,CAPTURE_VIDEO_ACTIVITY);
}
I found about view.performclick but do not know how to use for camera
Use MediaRecorder for this purpose. Though it will require more work but will give you much more control. Follow this link http://android-er.blogspot.tw/2011/04/start-video-recording-using.html. Since you don't reuire any button click for recording, keep a delay before starting the camera. Do it like this
myButton.setPressed(true); //you won't click the button
myButton.invalidate();
myButton.postDelayed(new Runnable() {
public void run() {
myButton.setPressed(false);
myButton.invalidate();
releaseCamera(); //release camera from preview before MediaRecorder starts
if(!prepareMediaRecorder()){
Toast.makeText(AndroidVideoCapture.this,"could not prepare MediaRecorder",Toast.LENGTH_LONG).show();
finish();
}
mediaRecorder.start();
}
},5000); //causes delay of 5 seconds befor recording starts
Ok, Make following, changes in your code.
Button play;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_c1_main);
play = findViewById ( R.id.btnPlay ); // assuming you have this button in your .xml file.
play.setOnClickListener ( new OnClickListener()
{
#Override
public void onClick ( View view )
{
Intent intent = new Intent("android.media.action.VIDEO_CAPTURE");
StartActivityForResult(intent,CAPTURE_VIDEO_ACTIVITY);
}
});
}
I like this site very much because I can find many useful solutions help me very much especially I'm beginner in android programming and this is my first question so I hope find helping from this great community.
The Problem:
I play video in my app and make it playing in full screen in landscape when user orient screen so I want to make video restart playing from the same point by using seekTo() and getCurrentPosition() - but the problem that video play many seconds after the position I mean that video seek to same point in time but when start play it add many seconds.
My Code:
//initialise everything
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
v = (VideoView) findViewById(R.id.videoView1);
v.setVideoPath(dir + videoName + ".3gp");
v.setMediaController(new MediaController(this));
if (savedInstanceState == null){
v.start();
}
else {
playingTime = savedInstanceState.getInt("restartTime", 0);
v.seekTo(playingTime);
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
if (file.exists()){
playingTime = v.getCurrentPosition();
v.stopPlayback();
outState.putInt("restartTime", playingTime);
}
}
I try many solution such as this
How to keep playing video while changing to landscape mode android
I'm using Galaxy Nexus to test my app .. I would be grateful for any hint.
Sorry for my bad English and thanks very much.
In your activity, keep everything normal. It boils down to saving the position when activity is recreated. Here is one approach:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initialise everything
//finally
if(savedInstanceState!=null) {
int seekValue = savedInstanceState.getInt("where");
//now seekTo(seekValue)
}
}
#Override
protected void onSaveInstanceState(Bundle outState) {
int seekValue; //set this to the current position;
outState.putInt("where", seekValue);
super.onSaveInstanceState(outState);
}
}
I am new in android and I have another (simple?) problem. I don't know how to stop Media Player. This is my simple code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view);
MediaPlayer mp;
mp = MediaPlayer.create(this, R.raw.sauronsound);
mp.setLooping(false);
mp.start();
#Override
protected void onDestroy()
{
// Stop play
super.onDestroy();
mp.stop();
}
}
After pressing back button app goes to my first activity but sound is on. When I leave an app it is on too. What should I do to turn off the sound?
As always excuse me for my poor English.
I solved the problem thanks to you Guys. Working code:
public class SauronEye extends Activity {
private MediaPlayer mp;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view);
mp = MediaPlayer.create(this, R.raw.sound);
mp.setLooping(false);
mp.start();
// Get instance of Vibrator from current Context
Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
v.vibrate(10000);
}
#Override
protected void onStop()
{
// Stop play
super.onStop();
mp.stop();
}
}
Is it correct (it works)? Thank you for helping me.
mp reference that you are using on onDestroy is different from the one you are using on onCreate. Move the MediaPlayer mp; line to outside the onCreate class.
Check this out http://developer.android.com/reference/android/media/MediaPlayer.html
You can call stop or pause based on your requirement.When you select back button your onpause would be called, in that method you can call mp.stop(), onDestroy would be called only when activity is completely destroyed
onDestroy is only called when the activity is killed by the system. Rather than placing it in onDestroy, you should put it in onPause(), which is what's called whenever your activity is moved to the background but remains in memory. (Which is what happens with a back button being pressed or leaving the app)
#Override
protected void onPause() {
super.onPause();
mp.stop();
}
you can call the override implements source codes really easily and add them each into your code. All you need to do is right click the insertion point where you want them and click on Source->Override/Implement Methods. It will bring up a dialog box and you click on the methods you need, try using ondestroy, onpause, onstop. For your code and after it implements each of them just add the following to each.
protected void onDestroy{
super.onDestroy();
mp.release();
}
protected void onStop{
super.onStop();
mp.stop();
}
protected void onPause{
super.onPause();
mp.pause();
}

I'm trying to make my app to play intro clip for only when I start activities.
But from my code it's always play the clip after wakeup before resume to app although I did not closed the app. What can I do to fix this prob?
From main:
startActivity(new Intent(this, MyIntro.class));
From MyIntro:
public class MyIntro extends Activity implements OnCompletionListener {
int a;
#Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.intro);
playIntro();
}
public void onConfigurationChanged(Configuration newConfig) {
setContentView(R.layout.intro);
}
public void onCompletion(MediaPlayer arg0) {
// TODO Auto-generated method stub
this.finish();
}
private void playIntro(){
setContentView(R.layout.intro);
VideoView video = (VideoView) this.findViewById(R.id.VideoView01);
Uri uri = Uri.parse("android.resource://real.app/" + R.raw.intro);
video.setVideoURI(uri);
video.requestFocus();
video.setOnCompletionListener(this);
video.start();
}
}
What function have you overridden in your main Activity - the one where you call
startActivity(new Intent(this, MyIntro.class))
?
I would assume it's onResume() and the line above is executed too many times, because of that. Read again the explanation of Activity lifecycle here, it's the first thing I do, when I have problems like that.
Get back to us with a little more info about the main Activity.
Evil hack:
Add a static pointer to your own activity, fill or override it when "onCreate" gets called. If it's null, play your movie, otherwise, don't.
You could do the same with a static boolean really.
private static boolean isRunning = false;
protected void onCreate(Bundle bundle) {
super.onCreate(bundle)
if(!isRunning)
{
isRunning = true;
//Play your video here
}
}
There are much more elegant and correct ways of doing this, but if you're in a hurry this will probably work.
