Ok so solution is check your android device version in mobile setting click on about device at last: you will know your android version there.

Now choose the same version for your netbeans android project.

Right click on project name click on properties and then change target with same as your android device.

(In my case android version was 4.4.2 so I selected the same for my project target)

Before to go ahead click on service tab next to project tab in netbeans then right click on Android device and click on restart ADB.

Finally you need to right click on project again and click on clear and build.

Now you can run with hope to get result.

Answer 3

The correct answer is close your Android Device Manager. None of these suggestions worked for me till I closed it.

Answer 4

Nothing worked for me except one solution...

Clearing the Intellij IDEA (Android Studio) .idea directory which contains configuration information worked for me:

Exit Android Studio Navigate to the project you are trying to debug Backup any files inside .idea that you modified (if your project checks any of these into VCS) Delete .idea directory Open the project in Android Studio

I just wanted to share my experience as I had the same error and there was no way to solve it using all the solutions you guys posted. I even deleted several times my virtual device, no way to make it work again.

In my App I have a custom permission com.example.CUSTOM_PERMISSION and I wanted to use it to protect my Main Activty from a confused deputy attack.

    <permission android:name="com.example.CUSTOM_PERMISSION"
            android:label="@string/permlab_deadlyActivity"
            android:description="@string/permdesc_deadlyActivity"
            android:permissionGroup="android.permission-group.COST_MONEY"
            android:protectionLevel="dangerous" />

. . .

    <activity
            android:permission="com.example.CUSTOM_PERMISSION"
            android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

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

Somehow that property android:permission was preventing my app to install and run on the virtual device, even though it could be compiled and build with Gradle successfully. Just after removing it, everything is fine again I am not sure the app is protected this way, I'm building another test app to try performing a confuse deputy and see if the declaration of the custom is just enough.

Hope this can help somebody that was getting mad like me!

There are two possibilities:

1.USB Debugging off :

• Start Developer Option of your devices
• Switch On USB Debugging

2.In Android-Studio : File -> Invalidate Caches / Restart
