The following is the code for my Android splash screen activity.
When it attempts to load another activity, the application crashes on Android 4.0 and 4.1.
I have no idea what's causing this because when it crashes, it does not log any error.
Has anyone come across anything like this befere?

I think that since the crashes do not occur with a higher Android version, the problem might be resulting from an incompatible OpenGL version.
You can use following Activity with some simple content. Inject the layout (see below) and register in the layout file an onclick-listener (method "forward"). In this method you can call your next activity:
public class SplashScreen extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
}
public void forward(View v){
startActivity(new Intent(this, MainActivity.class), 0);
}
}
splashscreen.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/splashscreen"
android:onClick="forward"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/ic_launcher" />
</LinearLayout>
Add in your AndroidManifest.xml:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.Black.NoTitleBar.Fullscreen" >
<activity
android:name=".SplashScreen"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".MainActivity" />
</application>
The class "MainActivity" represents your main activity and the class "SplashScreen" represents a simple splash screen.
I hope this will help you:)
The problem i see is that while calling the activity tag you still use .activity in the name attribute
i.e you used android:name=".activity.MainActivity"
instead of android:name=".MainActivity" both for splash screen activity and main activity.

I think you cannot added your splash screen in AndroidManifest.xml.plz check
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Splash extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
Thread logoTimer = new Thread() {
public void run() {
try {
int logoTimer = 0;
while (logoTimer < 500) {
sleep(100);
logoTimer = logoTimer + 100;
}
Intent newIntent = new Intent(Splash.this, MainActivity.class);
startActivity(newIntent);
} catch(InterruptedException e) {
e.printStackTrace();
} finally {
finish();
}
}
};
logoTimer.start();
}
}
in Android Manifest.xml
<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

You can't take decision on the basis of what the status of switch button when the app last opened because switch button will not retain its state, you have to save it somewhere when user changes it.
In that case what you can do is save the status of your switch button in sharedPreferences and in onCreate() of your launcher activity check that status and take decision accordingly. But in this case also if your launcher activity is Splash then it will be shown at least once for a fraction of a second until you make those checks.
P.S: You can't change the launcher activity which is declared inside your manifest.
First I created new LauncherActivity and removed previously created SettingsActivity
LauncherActivity
package="ahmer.afzal.myproject"
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
public class LauncherActivity extends Activity
{
public static String TRANSPARENT = "transparent";
private SharedPreferences sharedPref;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
sharedPref = getSharedPreferences("myPrefs", Context.MODE_PRIVATE);
if(!sharedPref.getBoolean(TRANSPARENT, false))
{
startActivity(new Intent(LauncherActivity.this, SplashActivity.class));
}
else
{
startActivity(new Intent(LauncherActivity.this, MainActivity.class));
}
finish();
}
}

I think you should better go through the guide for Mopub Banner Ads Integration which explains you the steps of banner ads integration.
Hope this will help you.
Use view in XML file
<com.mopub.mobileads.MoPubView
android:id="#+id/mrect_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:layout_weight="1" />
in activity Load code
pass id of view in below function ,unit id of ur app,and keywords of cataogry of ads
public void loadMoPubView(MoPubView moPubView, String adUnitId, String keywords) {
if (moPubView == null) {
Utils.logToast(LockScreenActivity.this, "Unable to inflate MoPubView from xml.");
//Toast.makeText(this, "Unable to inflate MoPubView from xml.", Toast.LENGTH_SHORT).show();
return;
}
try {
Utils.validateAdUnitId(adUnitId);
} catch (IllegalArgumentException exception) {
Utils.logToast(LockScreenActivity.this, exception.getMessage());
return;
}
moPubView.setBannerAdListener(this);
moPubView.setAdUnitId(adUnitId);
moPubView.setKeywords(keywords);
moPubView.setAutorefreshEnabled(true);
moPubView.loadAd();
}
I have created 2 activities.When i call second activity from first via intent then onCreate method of second activity does not called.Although first activity's onCreate method is called normally as it should be.
Below is the code for first activity.

import android.os.Bundle;

int counter;
Button add, sub;
TextView tView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
counter = 0;
add = (Button) findViewById(R.id.bAdd);
sub = (Button) findViewById(R.id.bSub);
tView = (TextView) findViewById(R.id.textView1);
// Intent in = new Intent(AC);
add.setOnClickListener(this);
sub.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bAdd:
tView.setText(++counter + "");
try {
Intent nextIntentView = new Intent(MainActivity.this, ShowValueActivity.class);
nextIntentView.putExtra("key", "counter");
startActivity(nextIntentView);
}
catch (Exception e) {
e.printStackTrace();
}
break;
case R.id.bSub:

<activity

you have
<activity
android:name=".ShowValueActivity"
android:label="#string/title_activity_show_value" >
</activity>
instead of
<activity
android:name=".ShowValue"
android:label="#string/title_activity_show_value" >
</activity>
Since your code reads
public class ShowValue extends Activity {
Though, why doesnt your application crash saying NoActivityFoundException ??
please have a look on manifest
change
<activity
android:name=".ShowValueActivity"
android:label="#string/title_activity_show_value" >
</activity>
to
<activity
android:name=".ShowValue"
android:label="#string/title_activity_show_value" >
</activity>
yours manifest should be like this
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.webesperto.webespertofirstapp"
android:versionCode="1"
android:versionName="1.0" >

android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >

android:name="com.webesperto.webespertofirstapp.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".ShowValue"
android:label="#string/title_activity_show_value" >
</activity>
</application>
</manifest>
Change your Second Activity name in class file like this:
package com.webesperto.webespertofirstapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
public class ShowValueActivity extends Activity {
TextView tv_showValue1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.show_value);
tv_showValue1 = (TextView) findViewById(R.id.tv_showValue);
Intent gotIntent = (Intent) this.getIntent();
Bundle gotBundle = gotIntent.getExtras();
tv_showValue1.setText(gotBundle.getString("key"));
}
}
It will work:)
Ok i am new to android development so please bear with me here. I am following the learning android book and have this problem where the refresh service wont work as it doesnt have the necessary permission. Can anyone tell me what is causing the issue?

The onOptionsItemSelected is used to call the refresh service.
Really Appreciate the help. Thanks!!
you need to declare permission in your manifest
<permission
android:name="com.example.yamba.permission.REFRESH"
android:protectionLevel="signature"
/>
You need to declare this REFRESH Permission in the manifest as well.
here is an example code of how to declare a permission
<permission
android:name="A_PERMISSION"
android:description="#string/broadcast_permission_desc"
android:label="#string/broadcast_permission_label"
android:permissionGroup="#string/broadcast_permission_group"
android:protectionLevel="signature" />

You have registered it dynamically , then why you are using receiver tag in manifest. I think you are messing up the code .
