I try to resolve this error from various methods in my Hello World App.These are;
-Go to Security-->Unknown sources.
-Go to About phone-->Build number.
-Update my manifest file whose picture is given below.
-Test app both on phone Y625 Huawei and on tablet T1-701u tab.
-Reboot android phone and android studio (version 3.4.1).
-Transfer apk file via data cable or airmove software.
But none of them works to solve the issue.
I develop my Hello World. Firstly i faced insufficient heap size error issue which has solved on the temporary basis. After build up my app, Parsing the package issue has emerged.
Manifest File:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.hw04">

<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

Whenever trying to run the app, getting the error:
"Could not identify launch activity: Default Activity not found".
I have seen a few other threads on the same issue, but the below solutions have not worked for me:
Invalidating gradle cache and re-running
Manually overriding in the edit configuration tab to select the default activity (it then says "The activity 'MainActivity' is not declared in AndroidManifest.xml" even though it is!)
Re-syncing the gradle files
Literally shuffling around the order of the activities in my manifest
Using the long name for my activities, but doesn't make any difference
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.mywebname">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity
android:name=".MainActivity"
android:screenOrientation="portrait"
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=".ListenScreen"
android:parentActivityName=".MainActivity"
android:screenOrientation="portrait">
</activity>
</application>
</manifest>
```
As you can see, I have clearly declared the activities (my app only has 2 so far), and I've put the intents around the ".MainActivity".
This answer worked for me after trying so many other tweaks, just adding the package name solved my problems
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.name">

You can only have to add the package name inside the manifest tag you can find your package name inside app.gradle file and you are good to go
Im taking the udacity coarse and for some reason android studio wont recognize my MainActivity class. Ive tried cleaning the project, rebuilding and making sure that the names were correct but nothing has solved my problem.
Android Manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="androidedx.example.activitylifecycle">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".Activity1"></activity>
<activity android:name=".Activity2" />
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Found the problem, this package name within the code I had to paste
package com.example.android.cookies;
Im not sure why specifically this caused the problem but atleast I solved it.
I am a new android programmer.
I created a simple "Hello World" app in android studio, but when I run it on an AVD, it gives the following error:
Unexpected error while executing: am start -n "com.example.ahrims.helloworld/com.example.ahrims.helloworld.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Error while Launching activity
EDIT 1:
Here is the manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ahrims.helloworld">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".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>
</application>
</manifest>
Edit 2:
The following is MainActivity file:
package com.example.ahrims.helloworld;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
I googled it, but did not find any useful answer.
Any help would be appreciated.
Thanks in advance.
Remove the .idea folder and gradle folder, then click "sync project with gradle" gradle files, after this process finished, you are able to run your app
I have two Android projects. One is a library and compiles a jar the other an executable which includes this jar on the build path.
I'm subclassing an activity in the jar in my project but when I start it I'm getting a ClassNotFoundException.
Here's the manifest with the activity in question being MainActivity:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.my.package.MyProject"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />
<application android:label="#string/app_name"
android:name=".MyApplication"
android:icon="#drawable/ic_launcher"
android:theme="#style/AppTheme">
<activity android:label="#string/app_name"
android:configChanges="orientation|keyboardHidden"
android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
And here is my MainActivity, where the QCARSamples package is found in my jar:
package com.my.package.MyProject;
import java.io.File;
import com.qualcomm.QCARSamples.ImageTargets.GraphicsEngineHook;
import com.qualcomm.QCARSamples.ImageTargets.VuforiaTrackingActivity;
import com.my.package.MyProject.R;
public class MainActivity extends VuforiaTrackingActivity{
private File blenderFile;
#Override
protected synchronized void updateApplicationStatus(final int appStatus){
return;
}
#Override
protected GraphicsEngineHook getGraphicsEngineHook() {
return new MyGraphicsEngineHook();
}
#Override
protected int getSplashScreenImageResource() {
return R.drawable.splash_screen_image_targets;
}
}
I also tried including the activity I'm subclassing in my manifest like so, but I was still getting the same error:
<activity>
<android:name="com.qualcomm.QCARSamples.ImageTargets.VuforiaTrackingActivity>
</activity>
Any ideas?
The problem is usually on the BuildPath.
Assuming you're using eclipse and ADT:
Right click on your project, select Build Path -> Configure Build Path -> Order and Export and make sure that your library is selected.
Remember to clean the project before trying again.
it could also be the class path as the guy suggested on the commented, on the manifest, instead of editing direct the XML, go to the Application tab, select the activity, click Browser, uncheck 'Display classes from sources of Project ...', and select the Activity from your library.
EDIT: SOLVED I JUST HAD TO WAIT FOR AWHILE
So I followed the simple "Hello Android" tutorial:
http://developer.android.com/resources/tutorials/hello-world.html
got everything set up fine.....stuff works but when I go to actually run it.....it just says "Android_" in my virtual device....
I tried running it on 2.1 2.2 2.3.1 and 2.3.3 VD's and get the same thing?
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);
}
}
Any ideas? My first venture into android is a failing one ;_;

"Android _" is the first loading emulator splash screen, so you are saying that you get stuck there? If that's the case, that has nothing to do with your code.
