my application crashes when i start new thread [duplicate]

This question already has an answer here:
Application crashes while starting the new thread
(1 answer)
Closed 9 years ago.
I have a class where I have implemented runnable and I start the thread in one of the function of this class, and I call this function from the main activity,I create the object of this class and call the method of thread class.My main activity code from where I call this class method is:
broadcast broadcastobject.threadfunc(messages);
My class where I create threads is:
public class broadcast {
private DatagramSocket socket;
String str;
private static final int TIMEOUT_MS = 10;
WifiManager mWifi;
EditText et;
DatagramPacket packet;
Button bt;
private static final int SERVERPORT = 11111;
private static final String SERVER_IP = "192.168.1.255";
public void threadfunc(String message){
str=message;
new Thread(new ClientThread()).start();
}
/*
private InetAddress getBroadcastAddress() throws IOException {
DhcpInfo dhcp = mWifi.getDhcpInfo();
if (dhcp == null) {
//Log.d(TAG, "Could not get dhcp info");
return null;
}
int broadcast = (dhcp.ipAddress & dhcp.netmask) | ~dhcp.netmask;
byte[] quads = new byte[4];
for (int k = 0; k < 4; k++)
quads[k] = (byte) ((broadcast >> k * 8) & 0xFF);
return InetAddress.getByAddress(quads);
}
*/
class ClientThread implements Runnable {
#Override
public void run() {
try {
socket = new DatagramSocket(SERVERPORT);
socket.setBroadcast(true);
// socket.setSoTimeout(TIMEOUT_MS);
} catch (SocketException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
InetAddress serverAddr = null;
try {
serverAddr = InetAddress.getByName(SERVER_IP);
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
packet = new DatagramPacket(str.getBytes(), str.length(),serverAddr,SERVERPORT);
try {
socket.send(packet);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}

This simply means that the emulator you are using does not have GPU emulation enabled. In Android SDK Tools R15 you can enable GPU emulation.You need to create a new emulator virtual device and set GPU emulation to true in Hardware properties.

code with thread crashes at startup (android beginner)

I am trying to make an application that passes through the audio samples obtained at the microphone to the speaker. This is the source code:
public class MainActivity extends Activity {
AudioManager am = null;
AudioRecord record =null;
AudioTrack track =null;
final int SAMPLE_FREQUENCY = 44100;
final int SIZE_OF_RECORD_ARRAY = 1024;
boolean isPlaying = false;
class MyThread extends Thread{
#Override
public void run(){
recordAndPlay();
}
}
MyThread newThread;
private void init() {
int min = AudioRecord.getMinBufferSize(SAMPLE_FREQUENCY, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);
record = new AudioRecord(MediaRecorder.AudioSource.VOICE_COMMUNICATION, SAMPLE_FREQUENCY, AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT, min);
int maxJitter = AudioTrack.getMinBufferSize(SAMPLE_FREQUENCY, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_16BIT);
track = new AudioTrack(AudioManager.MODE_IN_COMMUNICATION, SAMPLE_FREQUENCY, AudioFormat.CHANNEL_OUT_MONO,
AudioFormat.ENCODING_PCM_16BIT, maxJitter, AudioTrack.MODE_STREAM);
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setVolumeControlStream(AudioManager.STREAM_MUSIC);

newThread.start();
}
#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;
}
private void recordAndPlay() {
short[] lin = new short[SIZE_OF_RECORD_ARRAY];
int num = 0;
am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
am.setMode(AudioManager.MODE_IN_COMMUNICATION);
record.startRecording();
track.play();
while (true) {
num = record.read(lin, 0, SIZE_OF_RECORD_ARRAY);
track.write(lin, 0, num);
}
}
public void passStop(View view){

// /*

}
// */
}

Unfortunately, this program stops as soon as I try to run it through eclipse. This is wht I get in the logcat but I am not sure what it all means:

What could be the reason for this code crashing, and how can it be debugged? I am pretty sure it has something to do with Thread, because my other versions of this code where I have not included Thread at all do not crash on startup.

Variable newThread is not initialized in oncreate() method that's why it is giving nullpointer exception
add this in your init() method it will work
newThread=new Thread();

You are getting a null pointer exception because newThread has not been initialized yet and it is null when you try to start it. The thread doesn't have anything to do also. You should look at implementing a runnable, handler, and timer into your activity instead of a thread.

Use sub class with extending AsyncTask Class
class TestActivity extends AsyncTask <String, Void, String > {
protected String doInBackground(String... urls) {
// execution
}
protected void onPostExecute(String result) {
// post execution
}
protected void onPreExecute() {
super.onPreExecute();
// initial activities
}
}

If condition causing program to force close

I am doing an android app and i was thinking of creating a theme option. Well all I was thinking of doing was to allow the user to click on a image button which represented a theme. And when he clicks on it I start a new activity i.e i direct him to the home page. Also i have created a few integer variables which are set to 1 when the user clicks on a button.
Then in the other classes all i do is check if the variables are 1 or not and depending on that i apply the theme. By theme i mean i just change the background wallpaper. But this is not working. I mean the code works but if use an if loop to check the variable values and then apply the effects it causes an error.
Here's the complete code:
package com.example.themetest;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageButton;
import android.widget.LinearLayout;
public class MainActivity extends Activity implements OnClickListener{
ImageButton ib1;
ImageButton ib2;
int water=0;
int fire=0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ib1 = (ImageButton) findViewById(R.id.imageButton1);
ib2 = (ImageButton) findViewById(R.id.imageButton2);
ib1.setOnClickListener(this);
ib2.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.imageButton1:
water = 1;
Intent wi = new Intent("com.example.themetest.THEME");
startActivity(wi);
break;
case R.id.imageButton2:
fire = 1;
Intent fi = new Intent("com.example.themetest.THEME");
startActivity(fi);
break;
}
}
}
Here's the other class where i check which variable is set to 1 and apply the effect.
package com.example.themetest;
import java.io.InputStream;
import android.app.Activity;
import android.content.res.Resources;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.drawable.Drawable;
import android.os.Bundle;
import android.widget.EditText;
import android.widget.LinearLayout;
public class Theme extends Activity{
MainActivity main;
Resources res;
Drawable drawable;
LinearLayout linearLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.theme);
if(main.water==1){
res = getResources();
drawable = res.getDrawable(R.drawable.water_theme);
linearLayout = (LinearLayout)findViewById(R.id.ll);
linearLayout.setBackgroundDrawable(drawable);
}
else if(main.fire==1){
res = getResources();
drawable = res.getDrawable(R.drawable.fire_theme);
linearLayout = (LinearLayout)findViewById(R.id.ll);
linearLayout.setBackgroundDrawable(drawable);
}
else{
res = getResources();
drawable = res.getDrawable(R.drawable.ic_launcher);
linearLayout = (LinearLayout)findViewById(R.id.ll);
linearLayout.setBackgroundDrawable(drawable);
}
}
}
I can change the wallpaper without using the if loop, but i want to do it this way which is not working. Can anyone please tell me why?

I think the better way to do this is pass the name or code of the theme user selected along with the intent.
This might help: Passing data through Intent and receiving it

You cannot access other activities variables this way, a better way (for example) is to use a constant class..
public class Constants {
public static int water=0;
public staticint fire=0;
}
MainActivity:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.imageButton1:
Constants.water = 1;
Intent wi = new Intent("com.example.themetest.THEME");
startActivity(wi);
break;
case R.id.imageButton2:
Constants.fire = 1;
Intent fi = new Intent("com.example.themetest.THEME");
startActivity(fi);
break;
}
}
Theme:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.theme);
if(Constants.water==1){
res = getResources();
drawable = res.getDrawable(R.drawable.water_theme);
linearLayout = (LinearLayout)findViewById(R.id.ll);
linearLayout.setBackgroundDrawable(drawable);
}
else if(Constants.fire==1){
res = getResources();
drawable = res.getDrawable(R.drawable.fire_theme);
linearLayout = (LinearLayout)findViewById(R.id.ll);
linearLayout.setBackgroundDrawable(drawable);
}
else{
res = getResources();
drawable = res.getDrawable(R.drawable.ic_launcher);
linearLayout = (LinearLayout)findViewById(R.id.ll);

Lower version app not running in the Higher version in android

I have made my application using android SDK 2.2 version and now when I am running my app on android SDK 4.0.3 it's not running.
I have given the min and the max sdk in the manifest file.
I am new in android and want to run my app for the lower and higher versions both. Can anybody tell me how can I do this. Any help is appreciated.
Code for splash class
package com.Cricket_trivia.in;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.MotionEvent;
public class SplashScreen extends Activity {
protected int _splashTime = 5000;
private Thread splashTread;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
final SplashScreen sPlashScreen = this;
// thread for displaying the SplashScreen
splashTread = new Thread() {
#Override
public void run() {
try {
synchronized(this){
wait(_splashTime);
}
} catch(InterruptedException e) {}
finally {
finish();
Intent i = new Intent();
i.setClass(sPlashScreen, K_trivia_cricketActivity.class);
startActivity(i);
stop();
}
}
};
splashTread.start();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
synchronized(splashTread){
splashTread.notifyAll();
}
}
return true;
}
}

The reason why your app is crashing on 4.0.3 but not 2.2 is most likely because you are performing an expensive operation on the UI thread. Blocking the UI thread is very bad practice... don't do it!! Previous versions of Android (i.e. pre-ICS versions) didn't care when you did this and let your app run as is. In 4.0 and above, however, the OS checks against this and crashes your app if you ever perform a potentially expensive operation on the UI thread (such as a network connection, etc.).
You have provided basically no information on what the problem is in your question, so that's all I can really do to help you out.
Edit:
Does something like this work?
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Intent i = new Intent();
i.setClass(sPlashScreen, K_trivia_cricketActivity.class);
startActivity(i);
}
return true;
}

Don't you threads because it is creating the problem in the higher version. Use the code below to show the splash screen.
package com.Cricket_trivia.in;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.MotionEvent;
public class SplashScreen extends Activity {
protected int _splashTime = 5000;
private Thread splashTread;
MyCount counter = new MyCount(4000, 4000);
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
counter.start();
}
public class MyCount extends CountDownTimer
{
public MyCount(long csecond, long countDownInterval)
{
super(csecond, countDownInterval);
}
#Override
public void onFinish() {
finish();
Intent intent = new Intent();
intent.setClass(SplashScreen.this, K_trivia_cricketActivity.class);
startActivity(intent);
}
#Override
public void onTick(long arg0) {
// TODO Auto-generated method stub
}
}
}
I think it will work for you
