I'm having a problem with two network operations at the same time.
This is the code I'm working on:

Basically, my app uploads an audio file to the server and also inserts the file's metadata to the database server. But I'm getting an error. Please see my logcat errors below:

Note:
the saving of audio file's metadata is working, but the uploading of audio file seems to be not working.
Any ideas? I'm stuck with this problem. I really need your help. Thanks.
From what i see, you make 2 changes to the UI,
you either dismiss the dialog or closing the activity.
I think that you are closing the activity and then trying to do something with the dialog.
therefor you have a leaked window cause there is no activity.

This is your issue, add the android.permission.ACCESS_BLUETOOTH_SHARE permission to your manifest
I should add that this might not be your only error but it is the one causing this specific crash
I am learning java through a video tutorial but I am having a strange problem I create a class named OpenedClass in java and implements two classes. One is for OnClickListener and 2nd is OnCheckChangeListener but when i run the application on emulator it always give me the error for the calling OnClickListener. The code for my java class is:
package com.thenewboston.thenewboston;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.RadioGroup;
import android.widget.RadioGroup.OnCheckedChangeListener;
import android.widget.TextView;
public class OpenedClass extends Activity implements View.OnClickListener,
OnCheckedChangeListener {
TextView question, test;
Button returnData;
RadioGroup selectionList;
String gotBread;
String setData;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.send);
initialize();
private void initialize() {
// TODO Auto-generated method stub
question = (TextView) findViewById(R.id.tvQuestion);
test = (TextView) findViewById(R.id.tvTest);
returnData = (Button) findViewById(R.id.bResults);
selectionList = (RadioGroup) findViewById(R.id.rgAnswers);
selectionList.setOnCheckedChangeListener(this);
returnData.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent person = new Intent();
Bundle backpack = new Bundle();
backpack.putString("answer", setData);
person.putExtras(backpack);
setResult(RESULT_OK,person);
finish();
}
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
// TODO Auto-generated method stub
switch (checkedId) {
case R.id.rCrazy:
setData = "Probably Right !";
break;
case R.id.rSexy:
setData = "Definitely Right !";
break;
case R.id.rBoth:
setData = "Spot On !";
break;
}
test.setText(setData);
}
}
and this is the output for logcat:

as you guys can see that it tells me that the error is on line 44 and the line 44 in my code is
returnData.setOnClickListener(this);
I did not understand it at all when I comment this line it will show me the layout when I don't it didn't. Any idea why is this happening ?
From your comments below marcin_j post
<Button android:id="#+id/bReturn" // id is bReturn
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Return" >
</Button>
Change this
returnData = (Button) findViewById(R.id.bResults);
to
returnData = (Button) findViewById(R.id.bReturn);

This code
Intent f = new Intent(JHTTS.this, JHTTP.class);
is to start an Activity as if JHHTP was an Activity but it's not, its a Thread inside the Activity. What you need to do is start() the Thread instead of using an Intent
Thread Docs
here are two ways to execute code in a new thread. You can either subclass Thread and overriding its run() method, or construct a new Thread and pass a Runnable to the constructor. In either case, the start() method must be called to actually execute the new Thread.
Instead of using Intent try something like
JHTTP jhttp = new JHTTP();
jhttp.start();
I have been working on an app to use a phone's/tablet's camera flash as a flashlight. Everything seemed to be working fine but when I tested it on my Droid Bionic running Android 4.1.2, the app failed to turn on the flash even though it said it did. Here is the java code I used:
package com.example.flash;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.hardware.Camera;
import android.hardware.Camera.Parameters;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity {
private boolean isFlashOn = false;
private Camera camera;
private Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.buttonFlashlight);
Context context = this;
PackageManager pm = context.getPackageManager();
if(!pm.hasSystemFeature(PackageManager.FEATURE_CAMERA)) {
Log.e("err", "Device has no camera!");
Toast.makeText(getApplicationContext(),
"Your device doesn't have camera!",Toast.LENGTH_SHORT).show();
return;
}
camera = Camera.open();
final Parameters p = camera.getParameters();
button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
if (isFlashOn) {
Log.i("info", "torch is turned off!");
p.setFlashMode(Parameters.FLASH_MODE_OFF);
camera.setParameters(p);
isFlashOn = false;
button.setText("Tap to turn flashlight on.");
}
else {
Log.i("info", "torch is turned on!");
p.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(p);
isFlashOn = true;
button.setText("Tap to turn flashlight off.");
}
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
protected void onStop() {
super.onStop();
if (camera != null) {
camera.release();
}
}}
Is this code correct or did I miss something?

UPDATE
I think the key is you are running Android 4.1.2. Since Android 4.0, if you want to use the Camera Device, even if you only want to use the flash, you are forced to use a SurfaceView.
In the previous answer (below), I gave you a link to a Torch app which uses SurfaceView. Try it or adapt it to your code.
PREVIOUS ANSWER:
As stated in many other cases (like this one), you may be facing a Device-Specific issue that is quite common in the Android world.
Although getSupportedFlashModes() may return FLASH_MODE_TORCH on nearly every device, many of them don't actually support it.
Anyway, you could try these:
Use camera.startPreview(); after camera = Camera.open();
Try setting FLASH_MODE_OFF initially (before camera.startPreview();).
Check if this Torch app works in your device. In case it does, you have the source code to compare it to yours.
Download a Torch app from the Play Store to test if it's a device issue or not.
Post the issue in a Droid Bionic support forum.
UPDATE: I would say the final keyword is a problem in your code. Try changing it to:
//camera = Camera.open();
//final Parameters p = camera.getParameters();
button.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
if (isFlashOn) {
Log.i("info", "torch is turned off!");
cam.stopPreview();
cam.release();
isFlashOn = false;
button.setText("Tap to turn flashlight on.");
}
else {
Log.i("info", "torch is turned on!");
camera = Camera.open();
Parameters p = camera.getParameters();
p.setFlashMode(Parameters.FLASH_MODE_OFF);
camera.setParameters(p);
camera.startPreview();
p.setFlashMode(Parameters.FLASH_MODE_TORCH);
camera.setParameters(p);
isFlashOn = true;
button.setText("Tap to turn flashlight off.");
}
}
});
user the permission "android.permission.FLASHLIGHT" in the manifest
<uses-permission android:name="android.permission.FLASHLIGHT" />
<uses-permission android:name="android.permission.CAMERA" />
I am building a timetable app independently regarding school. I am now in the testing stage of my app and it just works fine on android version 2.3.6
However when I try to run it on a virtual device it's starts like normal.
However, after hitting a button which should execute the process to login, the apps returns the following errors:

The problem is the doLogin()-method, which performs Network tasks on the UI-thread.
Looking at your StackTrace you can see:
Caused by: android.os.NetworkOnMainThreadException
this is thrown since Android "Ice Cream Sandwich". To get rid of it, put the Network code in an AsyncTask.
See this older question: How to fix android.os.NetworkOnMainThreadException?
It looks like your executing your doLogin() method from the UI-Thread (possibly some onClick method in a button).
You should not do that, because Network access are potentially slow and could freeze the UI. Use the AsyncTask class instead (see http://developer.android.com/reference/android/os/AsyncTask.html)
Its always better practice to have the UI work on UI-Thread and
Non-UI work on Non-UI Thread, but from HoneyComb version of Android
it became a Law and won't allowed any network operation in the UI
thread
In your case doLogin() is a blocking call, which you are calling from UI thread, where as it should be on the Non-UI thread.
To get rid of this use AsyncTask or Thread.
