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 :
package com.apps.mathar;

public class SplashActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
// hideStatusBar();
setStatusColor();
try {
Constant.isFromPush = getIntent().getExtras().getBoolean("ispushnoti", false);
Constant.pushID = getIntent().getExtras().getString("noti_nid");
} 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() {
Intent intent = new Intent(SplashActivity.this,MainActivity.class);
startActivity(intent);
finish();
}
public void setStatusColor()
{
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
{

window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);

}

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..

The first, you don't need to set adapter multiple time, only set adapter at the first time in your method initView().
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
if(mTrainingDTO == null) {
mTrainingDTO = new ArrayList<>();
}
if(null == mTrainingDTOAdapter ) {
mTrainingDTOAdapter = new RecyclerAdapter(getActivity(), mTrainingDTO, FragmentTapNew.this);
}
lvToday.setAdapter(mTrainingDTOAdapter);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
After that, you don't need to call lvToday.setAdapter(mTrainingDTOAdapter);
many times. Just call mTrainingDTOAdapter.notifyDataSetChanged(); if having any changes in your data mTrainingDTO.

The errorlog - error:No adapter attached; skipping layout indicates that you've attached LayoutManager but you haven't attached an adapter yet, so recyclerview will skip layout. I'm not sure but, in other words recyclerView will skip layout measuring at the moment.
to prevent this errorLog Try to set an adapter with an empty dataSet i.e. ArrayList or
Attach LayoutManager just before you are setting your adapter.

Try this,
private void initViews() {
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity().getApplicationContext());
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
LinearLayoutManager mLinearLayoutManager = new LinearLayoutManager(getActivity());
lvToday.setLayoutManager(mLinearLayoutManager);
lvToday.setHasFixedSize(true);
lvToday.setNestedScrollingEnabled(false);
Thread t = new Thread(new Runnable() {
#Override
public void run() {
today();
}
});
t.start();
}

getting json data from google image search api with different start numbers

the google image search url looks like this https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=eden%20hazard&rsz=8&start=4 where the rsz parameter in the max images per page and the start parameter is the page number. I am able to get all imaged in a page. But have no idea to do that for say 20 pages, that is start= 0 ... 19. My code below shows how i did get the imaged from a page. Please let me know how i can make it get images for several pages. I tried using a for loop outside of me async task(okhttp enqueue).

You could create a method such as:
public String getImagesForPage(int page){
return "https://ajax.googleapis.com/ajax/services/search/images?v=1.0&q="
+ mEditedString +"&rsz=8&start=" + page;
}
Then:
for (start=0;start<20;start++){
if(isNetworkAvailable()) {
//using okHttp library to connect to imagesUrl and retrieve JSON Data
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(getImagesForPage(start)).
build();
Call call = client.newCall(request);
//runs the below code asynchronously
call.enqueue(new Callback() {
#Override
public void onFailure(Request request, IOException e) {
Log.v(TAG, "error from request");
}
#Override
public void onResponse(Response response) throws IOException {
try {
String jsonData = response.body().string();
//Log.v(TAG, jsonData);
if (!response.isSuccessful()) {
alertUserAboutError();
} else {
mSmalImagesUrls = getCurrentDetails(jsonData);
getActivity().runOnUiThread(new Runnable(){
#Override
public void run(){
mGridView =(GridView) rootView.findViewById(R.id.imagesGrid);//reference to gridview
ImagesGridAdapter adapter = new ImagesGridAdapter(getActivity(),mSmalImagesUrls);
mGridView.setAdapter(adapter);
}
});
}
...
}
I recommend you create a method just with your connection logic. This code will download the 20 pages of contents and update your gridView everytime a request finishes. So, in the end of it, you'll have your gridView with the last page content. To just store the content of the pages, create a HashMap<Integer,List<String>> to store the urls for each page.

list of images not showing up after search button is pressed

I am getting image urls using google image search apis. i use okhttp to connect to the url. this is done in my activity's oncreate method. in the oncreate() method of fragment i get all the image urls and store them in mSmallIMagesUrl, in the oncreateView() i try to display the images using a customized adapter. but when i run my app, hit the search button, it shows a blank page, when i go back and click the search button(there is always text in the search box) it shows images of the the previous search text. i dont know why it this,below is my code, please let me know what i am missing. thanks

Since you are making an asynchronous request, the response is not available immediately. You can display a ProgressBar while the list of images is being downloaded, and then display the list when it has completed downloading.
After that, notify your adapter that the dataset has changed.

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 android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.tv.socialgoal.R;
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) {
View view =getLocalActivityManager().startActivity(id,
newIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
this.setContentView(view);
}*/
}

break;
}
}
private Handler _handler = new Handler() {
public void dispatchMessage(Message msg) {

}
break;

}
};
// GET USER ACCESSTOCKEN AND USER ID
private boolean parseResponse(String response) {
String message = null;

boolean isUserInfoAvail = false;
try {

post = posts.getJSONObject("post");
message = post.getString("message");
if (message.equalsIgnoreCase("failure")) {
isUserInfoAvail = false;
} else {

}
} catch (JSONException e1) {

}

// SERVER RESPONSE METHOD
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.
