You need to set android:exported="true" in your AndroidManifest.xml file where you declare this Activity:

<activity
android:name="com.example.lib.MainActivity"
android:label="LibMain"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" >
</action>
</intent-filter>
</activity>

This is only for android studio

So I ran into this problem recently. The issue was in the build/run configuration. Apparently android studio had chosen an activity in my project as the launch activity thus disregarding my choice in the manifest file.

Click on the module name just to the left of the run button and click on "Edit configurations..." Now make sure "Launch default Activity" is selected.

The funny thing when I got this error was that I could still launch the app with from the device and it starts with the preferred Activity. But launching from the IDE seemed impossible.

Similar to Olayinka's answer about the configuration file for ADT: I just had the same issue on IntelliJ's IdeaU v14.

I'm working through a tutorial that had me change the starting activity from MyActivity to MyListActivity (Which is a list of MyActivity). I started getting Permissions Denial.

After much trial, toil and pain: In .idea\workspace.xml:

...
<configuration default="false" name="MyApp" type="AndroidRunConfigurationType" factoryName="Android Application">
<module name="MyApp" />
<option name="ACTIVITY_CLASS" value="com.domain.MyApp.MyActivity" />
...
</configuration>
...

I changed the MyActivity to MyListActivity, reloaded the project and I'm off to a rolling start again.

Not sure which IDE you are using, but maybe your IDE is overriding or forcing a specific starting activity?

Select your proper configuration for launching Application.

In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>

I needed the following instead:

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>

Correcting the path names fixed the problem.

If you are trying to test your app coded in android studio through your android phone, its generally the issue of your phone. Just uncheck all the USB debugging options and toggle the developer options to OFF. Then restart your phone and switch the developer and USB debugging on. You are ready to go!

if we make the particular activity as

android:exported="true"

it will be the launching activity. Click on the module name just to the left of the run button and click on "Edit configurations..." Now make sure "Launch default Activity" is selected.

Add android:exported="true" in your 'com.example.lib.MainActivity' activity tag.

From the android:exported documentation,

android:exported Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

From your logcat output, clearly a mismatch in uid is causing the issue. So adding the android:exported="true" should do the trick.

I was facing this issue on a react-native project and it came after adding a splash screen activity and making it the launcher activity.

This is the change i made in my android manifest XML file on the MainActivity configuration.

<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize"/>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />

I added the android:exported=true and the activity configuration looked like this.

 <activity
android:name=".MainActivity"
android:exported="true"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize"/>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />

AppActivity of any app which does not contain .SplashActivity at the end will throw this type of permisssion error. Make sure that AppActivity contain .SplashActivity at the end. If .SplashActivity is not present then it means app is not allowing for mobile automating
