Presently, I am working on app that sets the phone into the vibration mode or the ringer mode at the selected time. I have successfully implemented this using the alarmmanager in my application.
I want my app to remember all the pending intents when the phone is rebooted.
I found a sample code in the internet, but it seems to crash my app when the phone is rebooted. I don't know what's going wrong.
Here is alarmreciever.java
package ishan.khandelwal.vitsilentmode;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.AudioManager;
import android.widget.Toast;
public class AlarmReciever extends BroadcastReceiver
{
private AudioManager mAudioManager;
#Override
public void onReceive(Context context, Intent intent)
{
// TODO Auto-generated method stub
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
Intent serviceIntent = new Intent("ishan.khandelwal.vitsilentmode");
context.startService(serviceIntent);
}
mAudioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
mAudioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
// Show the toast
Toast.makeText(context, "Vibration Mode", Toast.LENGTH_SHORT).show();
}
}

Thanks for the help in advance.
Ok, the problem is that you have specified in your AndroidManifest the wrong/a nonexistent receiver implementation. You specified this:
<receiver
android:name=".receiver.StartMyServiceAtBootReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
The problem is you have no class called StartMyServiceAtBootReceiver. What you I think you should have is something like this:
<receiver
android:name=".AlarmReceiver"
android:enabled="true"
android:exported="true"
android:label="StartMyServiceAtBootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>

I'm trying using intent to add class to an application. I have made SecondAcitivity class and modified the manifest file as well. My application is running i.e. First activity Containing the button works well, but onclick on button the error comes and it does not displays a second activity.
This is my MainActivity.java file
package com.intent.usingintent;
import android.os.Bundle;
import android.content.Intent;
import android.app.Activity;
import android.view.View;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onClick(View view){
startActivity(new Intent("com.intent.SecondActivity"));
}
}
AndroidManifest.xml

In your App, your second activity in com.intent.usingintent package.And your intent action is com.intent.SecondActivity,and write <intent-filter> inside <activity> tag.
So in manifest file,Change
<activity
android:name="com.intent.SecondActivity"
android:label="SecondActivity" >
</activity>
<intent-filter>
<action android:name=".SecondActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
to
<activity
android:name="com.intent.usingintent.SecondActivity"
android:label="SecondActivity" >
<intent-filter>
<action android:name="com.intent.SecondActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
You have misplaced IntentFilter for the SecondActivity in the manifest. Put it insude <activity></activity>
Though you do no treally need that you can simply do startActivity(new Intent(this, SecondActivity.class));
in your manifest file instead of this
<activity
android:name="com.intent.SecondActivity"
android:label="SecondActivity" >
</activity>
replace with
<activity
android:name="com.intent.usingintent.SecondActivity"
android:label="SecondActivity" >
</activity>
and even in your java class also
startActivity(new Intent("com.intent.SecondActivity"));
replace this with
startActivity(new Intent("com.intent.usingintent.SecondActivity"));
change in manifest file
<activity
android:name="com.intent.usingintent.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="SecondActivity"></activity>
change in click event
Intent n=new Intent(MainActivity.this,SecondActivity.class);
startActivity(n);
I have finally finished my app and everything was working fine. I went back to add in the admob stuff and now it will not start in the emulator. it says it successfully installed the app on the emulator but it does not launch and the icon is not visible to try to manually run. I think the manifest is where my error is but I am unsure.

It looks like your main activity name is incorrect. Java is case sensitive and your application package name is
package="com.androidsleepmachine.gamble"
while your main activity class name is
com.AndroidSleepMachine.gamble.HOME
The ClassNotFoundException is being thrown because your Activity class name is incorrect in the manifest and isn't being found by the class loader.
It cannot find a class called:
com.AndroidSleepMachine.gamble.HOME
Why is "AndroidSleepMachine" using capital letters?
Why not just use:
android:name=".HOME"
...if your class is indeed called HOME.java? Case-sensitivity may be causing your issue.
com.AndroidSleepMachine.gamble.HOME is not the same as com.androidsleepmachine.gamble.HOME

it says that class is not there, but it IS there. I tried to configure things in my project's build path, but not too sure what to tweak there.
And here is how I start my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="business.premium"
android:versionCode="1"
android:versionName="1.0" >
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true"/>
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15"/>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/CustomTheme"
android:name="MyApplication"
android:debuggable="true">
<activity
android:name=".Problemio"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any thoughts on how to solve this, or what to look into? Thanks!
Its because you specified the "android:name" attribute in the application node in the manifest file.
Do not use the android:name attribute!
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException.
Remove it and it should work:
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:description="#string/help_text" >
This answer is taken from: java.lang.ClassNotFoundException on working app
I have an application thats been published awhile on Google play, I have been fixing reported bugs as they come in but recently this log below came in and I don't know what to make of it:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.mammothtooth.flightinfo/com.mammothtooth.flightinfo.ui.SplashActivity}: java.lang.ClassNotFoundException: com.mammothtooth.flightinfo.ui.SplashActivity in loader dalvik.system.PathClassLoader[/system/framework/com.google.android.maps.jar:/mnt/asec/com.mammothtooth.flightinfo-1/pkg.apk]

Does anyone know anything about this type of error log? My SplashScreenActivity is there and its defined as the entry point of the application in the manifest as follows:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/Theme.Sherlock" >
<uses-library android:name="com.google.android.maps" />
<activity
android:label="#string/app_name"
android:name=".ui.SplashActivity"
android:theme="#android:style/Theme.NoTitleBar"
android:configChanges="keyboard|keyboardHidden|orientation"
android:screenOrientation="portrait">
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Would the placing of the uses-library be an issue in the manifest?
I can't reproduce this issue on any of my android devices so any help is greatly appreciated in locating what might be the cause of this issue.
My app has been running okay until the recent Froyo update. After installing the Android 2.2 SDK, I can compile my code without any errors. However, when I run it, it just force closes:

The main startup class is com.handyapps.easymoney.EasyMoney. I placed a breakpoint at the start of the onCreate() method but I discovered it didn't even reach there. Somehow, the application just couldn't be loaded in Android 2.2... but it works perfectly fine for all the previous Android versions. Been trying to find the cause for the past 2 days but am totally stumped!!
I've found the solution! Just need to remove the android:name attribute from the application tag in the manifest... but the compiler should have given a warning or error.
From ClassCastException:
Thrown when a program attempts to cast
a an object to a type with which it is
not compatible.
I would go through the code and check the casts I am doing.
