Finally it displays the blank screen.

Anybody know how to solve these stacktrace error.Thanks in advance.

This error, as you can read on the question linked in comments above, results to be:

\"[...] a problem with loading {some} hardware module. This could be something to do with GPU support, sdcard handling, basically anything.\"

The step 1 below should resolve this problem. Also as I can see, you have some strange package names inside your manifest:

• package=\"com.example.hive\" in <manifest> tag,
• android:name=\"com.sit.gems.app.GemsApplication\" for <application>
• and android:name=\"com.sit.gems.activity\" in <activity>

As you know, these things do not prevent your app to be displayed. But I think:

the Couldn\'t load memtrack module error could occur because of emulators configurations problems and, because your project contains many organization problems, it might help to give a fresh redesign.

For better using and with few things, this can be resolved by following these tips:

---

1. Try an other emulator...

And even a real device! The memtrack module error seems related to your emulator. So change it into Run configuration, don\'t forget to change the API too.

---

2. OpenGL error logs

For OpenGl errors, as called unimplemented OpenGL ES API, it\'s not an error but a statement! You should enable it in your manifest (you can read this answer if you\'re using GLSurfaceView inside HomeActivity.java, it might help you):

<uses-feature android:glEsVersion=\"0x00020000\"></uses-feature>  
// or
<uses-feature android:glEsVersion=\"0x00010001\" android:required=\"true\" />

---

3. Use the same package

Don\'t declare different package names to all the tags in Manifest. You should have the same for Manifest, Activities, etc. Something like this looks right:

<!-- set the general package -->
<manifest xmlns:android=\"http://schemas.android.com/apk/res/android\"
    package=\"com.sit.gems.activity\"
    android:versionCode=\"1\"
    android:versionName=\"1.0\" >

    <!-- don\'t set a package name in <application> -->
    <application ... >

        <!-- then, declare the activities -->
        <activity
            android:name=\"com.sit.gems.activity.SplashActivity\" ... >
            <intent-filter>
                <action android:name=\"android.intent.action.MAIN\" />
                <category android:name=\"android.intent.category.LAUNCHER\" />
            </intent-filter>
        </activity>
        <!-- same package here -->
        <activity
            android:name=\"com.sit.gems.activity.HomeActivity\" ... >
        </activity>
    </application>
</manifest>  

---

4. Don\'t get lost with layouts:

You should set another layout for SplashScreenActivity.java because you\'re not using the TabHost for the splash screen and this is not a safe resource way. Declare a specific layout with something different, like the app name and the logo:

// inside SplashScreen class
setContentView(R.layout.splash_screen);

// layout splash_screen.xml
<TextView xmlns:android=\"http://schemas.android.com/apk/res/android\"
     android:layout_width=\"match_parent\"
     android:layout_height=\"match_parent\" 
     android:gravity=\"center\"
     android:text=\"@string/appname\" />  

Avoid using a layout in activities which don\'t use it.

---

5. Splash Screen?

Finally, I don\'t understand clearly the purpose of your SplashScreenActivity. It sets a content view and directly finish. This is useless.

As its name is Splash Screen, I assume that you want to display a screen before launching your HomeActivity. Therefore, you should do this and don\'t use the TabHost layout ;):

// FragmentActivity is also useless here! You don\'t use a Fragment into it, so, use traditional Activity
public class SplashActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // set your splash_screen layout
        setContentView(R.layout.splash_screen);

        // create a new Thread
        new Thread(new Runnable() {
            public void run() {
                try {
                    // sleep during 800ms
                    Thread.sleep(800);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                // start HomeActivity
                startActivity(new Intent(SplashActivity.this, HomeActivity.class));
                SplashActivity.this.finish();
            }
        }).start();
    }
}  

I hope this kind of tips help you to achieve what you want.
If it\'s not the case, let me know how can I help you.

回答2:

I had the same error. Creating a new AVD with the appropriate API level solved my problem.

回答3:

I faced the same problem but When I changed the skin of AVD device to HVGA, it worked.

回答4:

For people using Xamarin

I found that setting the linking to Sdk Assemblies Only does the trick: Project -> Properties -> Android Options -> Linker tab -> Linking:

回答5:

Enabling ADB Integration solved my problem.

In Menu: Tools -> Android -> Enable ADB Integration

回答6:

do you called the ViewTreeObserver and not remove it.

    mEtEnterlive.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
         // do nothing here can cause such problem
    });

回答7:

I had this issue too, also running on an emulator.. The same message was showing up on Logcat, but it wasn\'t affecting the functionality of the app. But it was annoying, and I don\'t like seeing errors on the log that I don\'t understand.

Anyway, I got rid of the message by increasing the RAM on the emulator.
