Why read logcat in loop read only one time

Why read logcat in loop read only one time - java

I run my service (write logcat to file) on any emulators and real devices from 2.3.3 to 4.1. All OK.
On this devices generated right log:
--------- beginning of /dev/log/main
--------- beginning of /dev/log/system
I/ActivityManager( 3386): START {act=android.intent.action.MAIN cat=[android.intent.category.HOME] flg=0x10000000 cmp=com.android.launcher/com.androWAcivtMaae( 36:IvldakgNme W/ActivityManager( 3386): Duplcaefns eus orcitRod45c6 o.vnotsolet.tiiyilg
I/ActivityManager( 3386): Displayed com.android.calculator2/.Calculator: +9s374ms<br>
.....
.....
But when I run service on 4.1.2 (samsung (google) Nexus S (soju, crespo), SDK 16, flash 485486, build JZO54K) or 2.3.6, my service stoped after one line in logs.
On this devices generated wrong log:
--------- beginning of /dev/log/main
Only print one line and nothing.... Service stay in memory, but not work right...
This is my code

What is wrong?

On 4.1.2., Only rooted and system applications can access logcat. If rooted, you could use "su logcat".
https://groups.google.com/forum/?fromgroups=#!topic/android-developers/6U4A5irWang
I suspect that you will find that this line throws an exception which you do not handle (bad practice btw - if you had a proper catch, you would have found this I think).
procLogcatAM = localRuntimeAM.exec( sLogcatAM);
Otherwise, check for the Android version and do something different or check for the permission refusal. Or, restrict your app to < 4.1.

React Native: Override Error on Package without Duplicate

I'm trying to use the react-native-camera package but when I added this to my project, I wasn't able to see the camera, instead it was loading and a warning. Then I search on the internet for this warning and saw that I had to link this library manually and so I did. But when I try to build I got this:

Well, the message sais it pretty clear in my opinion. Rect-Native 0.60+ uses autlinking to link native packages, so you are not require to use react-native link react-native-camera anymore.
Which means you don't need to import and have packages.add(new RNCameraPackage()); in your MainApplication.java
protected List<ReactPackage> getPackages() {
#SuppressWarnings("UnnecessaryLocalVariable")
List<ReactPackage> packages = new PackageList(this).getPackages();
packages.add(new RNCameraPackage()); // Remove this line and the import statement
return packages;
}
You also need to remove all the other things that were added when running the react-native link command. Reinstall and your app should open now.
LE:
As backup, you can turn off autolinking for specific packages like below. Edit or create react-native.config.js add have the following.
module.exports = {
dependencies: {
'react-native-camera': {
platforms: {
android: null, // disable Android platform, other platforms will still autolink if provided
},
},
},
};

Why is my ACTION_SEND working on API 25+ perfectly, but messes up on previous APIs?

So I have a Share button that will share an image and a body of text.
On Nougat (API 25) and Oreo (API 26), it works absolutely perfectly. But when it comes to a couple older version it doesn't work as expected.
Marshmallow (API 23): Inserts the image just fine but no body of text.
Lollipop (API 22): Crashes when you push the Share button with popup error "Unfortunately, Messaging has stopped." LOGCAT isn't showing me any errors when this happens.
Here is my share button code:
if (id == R.id.action_shareWine) {
Intent intentShare = new Intent(Intent.ACTION_SEND);
intentShare.putExtra(intentShare.EXTRA_STREAM, imageURI);
intentShare.setType("image/*");
intentShare.putExtra(Intent.EXTRA_TEXT, "body of text goes here");
if (intentShare.resolveActivity(getPackageManager()) != null) {
startActivity(intentShare);
}
return true;
}
Here is a picture to give a visual idea of whats going on:
Anyone have any ideas what could be going on here?
UPDATE 1
Here is the crash log for the Lollipop emulator:
FATAL EXCEPTION: Mms-1
Process: com.android.mms, PID: 7570
java.lang.IllegalStateException: Couldn't read row 0, col 0 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
Which I'm not sure why it is happening because the cursor is loading the image just fine in an ImageView in that same activity.

Call addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION) on the ACTION_SEND Intent, to allow third parties the ability to read the content identified by the Uri.
Also, since the image would appear to be a JPEG (based on the file extension), the MIME type is image/jpeg, not image/* or image/png.

Having trouble exporting SQLite Database in Android

I have an application that I want to export the current SQLite database to the Internal storage Downloads folder of the device. I am getting the below error.
java.io.FileNotFoundException:
/storage/emulated/0/Download/Pipe_Tally: open failed: EACCES
(Permission denied)
I have what I think are the correct permissions included in the AndroidManifest.xml file for reading and writing to storage.

}
return true;
} else {

}
}
This is the onOptionsItemSelected() method that has the switch in it to handle the menu and what is selected. The case:R.id.menu_save_and_export:
is where I am checking if checkSdCardPermissions() method is true, then calling the backUpDatabase() method.

I really appreciate any help or advice with fixing this issue. Thank you.

You have a android:maxSdkVersion="18" set on the WRITE_EXTERNAL_STORAGE permission. If you are running on a phone with SDK > 18 the app will not have permission to WRITE_EXTERNAL_STORAGE. So I suggest you remove the android:maxSdkVersion attribute. Read the documentation.
android:maxSdkVersion : The highest API level at which this permission should be granted to your app. Setting this attribute is useful if the permission your app requires is no longer needed beginning at a certain API level.
Change it as follows,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Can someone help me with Android RemoteControlClient?

I'm trying to get the RemoteControlClient set up so my app's music can be controlled by the widget that pops up on the lock screen (like SoundCloud, Google Play Music, and other music/video apps work). I'm not sure what's wrong with my code and why it isn't correctly hooking, but here's what I have so far...
A class called MusicService that tries to handle the updates to the RemoteControlClient
public class MusicService extends Service
{
public static final String ACTION_PLAY = "com.stfi.music.action.PLAY";
private RemoteController controller = null;
#Override
public void onCreate()
{
super.onCreate();
System.out.println("Creating the service.");
if(controller == null)
{
controller = new RemoteController();
}
}
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
String action = intent.getAction();
System.out.println("Got an action of " + action);
/* Logic to get my Song cur */
controller.register(this);
controller.updateMetaData(cur);
return START_STICKY;
}
#Override
public void onDestroy()
{
super.onDestroy();
System.out.println("Destorying MusicService");
}
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
}
This uses a class I have called RemoteController which houses my RemoteControlClient.
public class RemoteController {
private RemoteControlClient remoteControlClient;
private Bitmap dummyAlbumArt;
public void register(Context context)
{
if (remoteControlClient == null)
{
System.out.println("Trying to register it.");
dummyAlbumArt = BitmapFactory.decodeResource(context.getResources(), R.drawable.dummy_album_art);
AudioManager audioManager = (AudioManager) context.getSystemService(context.AUDIO_SERVICE);
ComponentName myEventReceiver = new ComponentName(context.getPackageName(), MediaButtonReceiver.class.getName());
audioManager.registerMediaButtonEventReceiver(myEventReceiver);
// build the PendingIntent for the remote control client
Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
mediaButtonIntent.setComponent(myEventReceiver);
// create and register the remote control client
PendingIntent mediaPendingIntent = PendingIntent.getBroadcast(context, 0, mediaButtonIntent, 0);
remoteControlClient = new RemoteControlClient(mediaPendingIntent);
remoteControlClient.setTransportControlFlags(RemoteControlClient.FLAG_KEY_MEDIA_PLAY_PAUSE
| RemoteControlClient.FLAG_KEY_MEDIA_NEXT
| RemoteControlClient.FLAG_KEY_MEDIA_PREVIOUS
| RemoteControlClient.FLAG_KEY_MEDIA_PLAY
| RemoteControlClient.FLAG_KEY_MEDIA_PAUSE
);
audioManager.registerRemoteControlClient(remoteControlClient);
}
}
/**
* Update the state of the remote control.
*/
public void updateState(boolean isPlaying)
{
if(remoteControlClient != null)
{
if (isPlaying)
{
remoteControlClient.setPlaybackState(RemoteControlClient.PLAYSTATE_PLAYING);
}
else
{
remoteControlClient.setPlaybackState(RemoteControlClient.PLAYSTATE_PAUSED);
}
}
}
/**
* Updates the state of the remote control to "stopped".
*/
public void stop()
{
if (remoteControlClient != null)
{
remoteControlClient.setPlaybackState(RemoteControlClient.PLAYSTATE_STOPPED);
}
}
public void updateMetaData(Song song)
{
if (remoteControlClient != null && song != null)
{
System.out.println("Updating metadata");
MetadataEditor editor = remoteControlClient.editMetadata(true);
editor.putBitmap(MetadataEditor.BITMAP_KEY_ARTWORK, dummyAlbumArt);
editor.putLong(MediaMetadataRetriever.METADATA_KEY_DURATION, (long)1000);
editor.putString(MediaMetadataRetriever.METADATA_KEY_ARTIST, "Artist");
editor.putString(MediaMetadataRetriever.METADATA_KEY_TITLE, "Title");
editor.apply();
updateState(true);
}
}
/**
* Release the remote control.
*/
public void release() {
remoteControlClient = null;
}
}
Every time I want to update the widget, I call startService(new Intent(MusicService.ACTION_PLAY));. It looks like it correctly creates the service, and it always gets to the point where it says "Updating metadata", but for some reason when I lock my screen and unlock it, I don't see any widget on my lock screen.
Below is the important parts of my manifest as well, seeing as that could somehow cause the issue...
<?xml version="1.0" encoding="utf-8"?>

<data android:scheme="http" />
</intent-filter>
</service>
<receiver
android:name=".music.MediaButtonReceiver"
android:exported="false" >
</receiver>
</application>
Right now my MediaButtonReceiver doesn't really do much of anything. I'm just trying to get the hooks set up. If you want, this is my MediaButtonReceiver class...
public class MediaButtonReceiver extends BroadcastReceiver
{
#Override
public void onReceive(Context context, Intent intent)
{
System.out.println("Receiving something.");
if (intent.getAction().equals(Intent.ACTION_MEDIA_BUTTON))
{
final KeyEvent event = (KeyEvent) intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
if (event != null && event.getAction() == KeyEvent.ACTION_UP)
{
if (event.getKeyCode() == KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE)
{
System.out.println("You clicked pause.");
}
else if(event.getKeyCode() == KeyEvent.KEYCODE_MEDIA_PLAY)
{
System.out.println("You clicked play.");
}
else if (event.getKeyCode() == KeyEvent.KEYCODE_MEDIA_NEXT)
{
System.out.println("You clicked next.");
}
else if (event.getKeyCode() == KeyEvent.KEYCODE_MEDIA_PREVIOUS)
{
System.out.println("You clicked previous.");
}
}
}
}
}

if you can't see remoteControlClient on lock screen you must implement audio focus. You can look here

EDIT:
Thanks for the code but there's still a problem. When I run the Application the textview displays his default message. During this time, the logcat displays a lot of messages:
http://pastebin.com/244grjYt
and at the end the app crashes

Essentially, this is what the other answers are about. Since you haven't check anything as answer, maybe this will help.
public class MyClass extends Activity {
TextView textview;
public void onCreate(Bundle bundle) {
super.onCreate(savedInstanceState);
setContentView(R.layout.classement);
textview = (TextView)findViewById(R.id.textview);
new NetworkOperation().execute();
}
private class NetworkOperation extends AsyncTask<Void, Void, String> {
protected String doInBackground(Void... params) {
try {
URL oracle = new URL("http://www.nationalleague.ch/NL/fr/");
URLConnection yc = oracle.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(yc.getInputStream()));
String inputLine;
String s1 = "";
while ((inputLine = in.readLine()) != null)
s1 = s1 + inputLine;
in.close();
int Berne = s1.indexOf(">SC Bern</td>");
String s3 = String.valueOf(Berne);
return s3;
}
catch (IOException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String result) {
textview.setText(result);
}
}
}

You cannot make a network connection (HTTP connection) i the ui thread, try to move the call to getCode.test() into another thread or better into an AsyncTask..

You are facing NetworkOnMainThread Exception which is quite common on Emulators that are running on API level 11 and more when you are writing Network Related code in UI Thread. You change your code into doInBackground() of an AsyncTask and run it.
In your case as you are throwing Exception in test() it will not crash your app because Exceptions are caught by Exception.
Example Code:
class FetchResultTask extends AsyncTask<Void,Void,String>
{
protected String doInBackground()
{
//your network related code.
}
protected void onPostExecute(String result)
{
super.onPostExecute(result);
//set the result to TextView here.
}
}
