I found this error in logcat hw_get_module_by_class: module name gralloc

I run my App on my phone. Everything works perfectly.. But after i check in my logcat for the debug.
It's show me this error.
E/HAL: hw_get_module_by_class: module name gralloc
E/HAL: hw_get_module_by_class: module name gralloc
It's show when user run the app for the first time. It's show just in time the app show splash screen. I'm not sure which code that make this thing happen.
So i'll show you my splash code and my fragment home code.
so this is my splasactivity code :

} catch (Exception e) {
Constant.isFromPush = false;
}
try {
Constant.isFromNoti = getIntent().getExtras().getBoolean("isnoti", false);
} catch (Exception e) {
Constant.isFromNoti = false;
}
JsonUtils jsonUtils = new JsonUtils(SplashActivity.this);
Resources r = getResources();
float padding = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, Constant.GRID_PADDING, r.getDisplayMetrics());
Constant.columnWidth = (int) ((jsonUtils.getScreenWidth() - ((Constant.NUM_OF_COLUMNS + 1) * padding)) / Constant.NUM_OF_COLUMNS);
if(!Constant.isFromNoti) {
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
openMainActivity();
}
}, 2000);
} else {
openMainActivity();
}
}
private void openMainActivity() {

finish();

Once more, i'm sure what's going on here.
I'm looking this error since 3 days ago but i have checked my code, i dont know what is wrong with this code.

This kind of error occurs when you have a loop that doesn't terminate.I also faced the similar kind of situation and It took me literally two days to find out the root cause of problem.
My problem was:
When I run the above code, I used to get this kind of error
hw_get module_by class _gralloc... .
I was really frustrated because I was not able to find out the root cause and luckily I found out that the above section of the code was the main cause because the loop never goes to terminate in the above section and when I found about the problem main cause I replaced it by:
Then, the problem was solved..
So maybe your problem lies within the loop or similar kind of situations..

Passing Boolean value from fragments to activity

I am new to android development and I am trying to pass a Boolean value from dialog fragment to the activity.
the boolean value is supposed to be decided by the user(depends on which button user clicked). However, the boolean immediately turned to false without clicking any button.
I have tried various method recommended I found on internet but none of them works for me(I guess I have some part screwed up...), these method include:
-broadcasting
-implementing interface
-intent.putExtra
and below is the code that I have came up with, could anyone help me take a look? Any help is appreciated.

LosingDialogFragment:
package com.example.fuj.valorsafeworldbytrade;
import android.app.Activity;
import android.content.Intent;

import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
/**

*/
public class LosingDialogFragment extends DialogFragment{
public static final String LOSING_FRAGMENT = "LOSING";
public boolean tryAgainEnabled;
Intent intent = new Intent();
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_lose, container, false);;
//the following code is used to set the boolean value after the user click the button

#Override

getDialog().setTitle(LOSING_FRAGMENT);
return rootView;
}
}
I am also sorry that I am not the best with English, if any things is not clear or not polite because of my poor English, please kindly let me know. I apologize in advance for any mistakes I have made.

It's because you check the value of tryAgainEnabled exactly right after showing the Dialog. Dialog starts Asynchronously, It means that it starts in diffrent Thread and your current thread doesn't wait for dismissing Dialog, So this line of your code if(losingDialogFragment.tryAgainEnabled){ runs exactly after you show dialog, befor you set value to tryAgainEnabled. Because the default value of boolean is always false, you will get false everytime.
I suggest that use listener for this:
Dialog:
public class LosingDialogFragment extends DialogFragment {
public static final String LOSING_FRAGMENT = "LOSING";
public boolean tryAgainEnabled;
Intent intent = new Intent();
private View.OnClickListener onTryAgainButtonClickLisnter;
private View.OnClickListener onGiveUpButtonClickLisnter;
#Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.fragment_lose, container, false);;
final Button tryAgainButton = (Button)rootView.findViewById(R.id.try_again_button);
tryAgainButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onTryAgainButtonClickLisnter!=null)
onTryAgainButtonClickLisnter.onClick(v);
}
});
Button giveUpButton =(Button)rootView.findViewById(R.id.give_up_button);
giveUpButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(onGiveUpButtonClickLisnter!=null)
onGiveUpButtonClickLisnter.onClick(v);
}
});
getDialog().setTitle(LOSING_FRAGMENT);
return rootView;
}
public void setOnTryAgainButtonClickLisnter(View.OnClickListener onTryAgainButtonClickLisnter) {
this.onTryAgainButtonClickLisnter = onTryAgainButtonClickLisnter;
}
public void setOnGiveUpButtonClickLisnter(View.OnClickListener onGiveUpButtonClickLisnter) {
this.onGiveUpButtonClickLisnter = onGiveUpButtonClickLisnter;
}
}
In your activity call dialog like this:
LosingDialogFragment losingDialogFragment = new LosingDialogFragment();
losingDialogFragment.setOnTryAgainButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
tryAgain();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.setOnGiveUpButtonClickLisnter(new View.OnClickListener() {
#Override
public void onClick(View v) {
giveUp();
losingDialogFragment.dismiss();
}
});
losingDialogFragment.show(fragmentManager, "");

Declare public boolean tryAgainEnabled; in your Stage Activity and youd can update that variable using ((Stage)context).tryAgainEnabled.

Grid-view is not formed in horizontal-scrolling-pages like home screen when app is in Background or Process is died

I am developing Horizontal Scrolling pages and tabs
MY app is working well in all devices in foreground, but when it goes to background, after one hour, the logs saying that Process com.example.myapp has died. When i reopen the app , the gridview data is not appearing but when scrolling horizontally , getView() method displaying all data like images and text.
that means app has data but view is not formed when process has died. And if i press back button and re-open the app, It is working good

Actually, some data is being saved with onSavedInstaceState(). The data is not being deleted when process has been killed on LowMemory.
I fixed this with

}
Just do not call super class. Just comment like above

Calling activitygroup from customlistadapter

I am working on an android app which is having functionality of tabs.
Everything is working fine but I am not able to call activtygroup from listadapter.
Here is my code for list adapter:
import java.util.ArrayList;
import android.app.Activity;
import android.app.ActivityGroup;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;

import com.tv.socialgoal.imageloader.ImageLoader;
public class AllyListAdapter extends BaseAdapter{
Activity ctx;
ArrayList<Object> alist;
private ImageLoader imageLoader;
AllyBean allyBean;
private String photoPath;
public AllyListAdapter(Activity ctx, ArrayList<Object> alist) {
super();
this.ctx = ctx;
this.alist = alist;
imageLoader=new ImageLoader(ctx);
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return alist.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
#Override
public View getView(int position, View arg1, ViewGroup arg2) {
LayoutInflater linf=(LayoutInflater) ctx.getSystemService(ctx.LAYOUT_INFLATER_SERVICE);
View v=linf.inflate(R.layout.ally_list_row, null);
TextView tv=(TextView)v.findViewById(R.id.allyName);
ImageView profileImage=(ImageView)v.findViewById(R.id.ally_image);
Button inviteBtn=(Button)v.findViewById(R.id.invite_btn);
//SHOW DATA FROM LIST
allyBean=(AllyBean)alist.get(position);
tv.setText(allyBean.getName());
photoPath=allyBean.getAvatar();
profileImage.setTag(photoPath);
imageLoader.displayImage(photoPath, ctx, profileImage, false);
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent=new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
});
return v;
}
/*public void replaceContentView(String id, Intent newIntent) {

public void serverResponse(String response, int processid) {
Message msg = new Message();
msg.arg1 = processid;
msg.obj = response;
_handler.dispatchMessage(msg);
}
}
Please suggest me how to call activtygroup from listadapter.

Make it like this you can access everything by doing like this.
public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
.......
}
class AllyListAdapter extends BaseAdapter
{
//Now you can call everything from ActivityGroup
}
}
Hope this will help you.

According to the android developper reference, you may use Fragments.
ActivityGroup is deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.
You can try this trick.
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(ctx instanceof ActivityGroup){
Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.getParent().startActivity(intent);
}
else{
Intent intent = new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
}
});
If it doesn't work just use internal class for your adapter in your AddRemoveFriendScreen class.

Android create intent to start activity

I have an app, which consists of a tabhost. I am using a AsyncTask to perform some internet work in the background. Now in the onPostExecute, I want it to start a new activity. When I create a new intent, the new activity is shown, but there are no tabs.. it's just the activity.
Now i've read online how to do this, And i've managed to get into the right direction i think. This is the entire code:
package com.appsoweb.kvodeventer;
import org.json.JSONObject;
import android.app.Activity;
import android.app.ActivityGroup;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class KVOMeldingen extends ActivityGroup {
public static final JSONObject jsonResult = null;
Button bLogin, bCreateAccount, bResetPassword;
EditText etUsername, etPassword;
static String Username;
static String Password;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.meldingen);
final EditText etUsername = (EditText) findViewById(R.id.etUsername);
final EditText etPassword = (EditText) findViewById(R.id.etPassword);
Button bLogin = (Button) findViewById(R.id.bLogin);
Button bCreateAccount = (Button) findViewById(R.id.bCreateAccount);
Button bResetPassword = (Button) findViewById(R.id.bResetPassword);
bLogin.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (etUsername.length() <= 0) {
etUsername.setError("Veld mag niet leeg zijn");
} else if (etPassword.length() <= 0) {
etPassword.setError("Veld mag niet leeg zijn");
} else {
Username = etUsername.getText().toString();
Password = etPassword.getText().toString();
}
LoginTask NDLT = new LoginTask();
NDLT.execute();
}
});
bCreateAccount.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// Doe iets hier.......
}
});
bResetPassword.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Doe iets hier........
}
});
}
public static String getUsername() {
return Username;
}
public static String getPassword() {
return Password;
}
class LoginTask extends AsyncTask<Void, Void, JSONObject> {
ProgressDialog waitingDialog;
#Override
protected void onPreExecute() {
waitingDialog = new ProgressDialog(KVOMeldingen.this);
waitingDialog.setMessage("Laden...");
waitingDialog.show();
super.onPreExecute();
}
#Override
protected JSONObject doInBackground(Void... params) {
JSONObject json = JsonFunctionLogin
.getJsonLoginResult("http://api.crossalertdeventer.nl/login.json");
return json;
}
#Override
protected void onPostExecute(JSONObject json) {
super.onPostExecute(json);
if (waitingDialog.isShowing()) {
waitingDialog.dismiss();
Log.d("iets gebeurt", "gedaan");
}
try {
String LoginResult = json.getString("login");
String UserIdResult = json.getString("user_id");
Log.d("LoginResult", LoginResult);
Log.d("LoginUserId", UserIdResult);
json = null;
Intent intent = new Intent(KVOMeldingen.this, KVOCards.class);
View view = getLocalActivityManager().startActivity("KVOCards", intent
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
replaceView(view);
} catch (Exception e) {
Log.e("KVOMeldingen", "error" + e.getMessage());
}
}
public void replaceView(View v){
setContentView(v);
}
}
}
As you can see: I've created a View that will be shown trough an Intent. But the intent doesn't launch after the onbackground. It gives me an error:
Unable to start Activity componentInfo Unable to add window ... Token..... is not valid... Is your application running?
What am i doing wrong?
Thnx in advance

Starting a new Activity means you are navigating from your TabActivity to a normal Activity. Obviously you can't find a tab in Activity. You have to replace views instead of creating Activities.
Here is a good example of how to use ActivityGroup with TabActivity.
