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    lt PreferenceScreen xmlns android  http   schemas android com apk res android  gt       lt Preference         android key  pref edit recipe key          android title  Add Edit Recipe  gt           lt intent             android action  android intent action VIEW              android targetPackage  com ssimon olddirectory              android targetClass  com ssimon olddirectory RecipeEditActivity   gt       lt  Preference gt   lt  PreferenceScreen gt     I needed the following instead    lt PreferenceScreen xmlns android  http   schemas android com apk res android  gt       lt Preference         android key  pref edit recipe key          android title  Add Edit Recipe  gt           lt intent             android action  android intent action VIEW              android targetPackage  com ssimon newdirectory              android targetClass  com ssimon newdirectory RecipeEditActivity   gt   lt  Preference gt    Correcting the path names fixed the problem

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

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

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    x000D   x000D   lt activity x000D          android name   MainActivity  x000D          android label   string app name  x000D          android configChanges  keyboard keyboardHidden orientation screenSize  x000D          android windowSoftInputMode  adjustResize   gt  x000D         lt activity android name  com facebook react devsupport DevSettingsActivity    gt  x000D   x000D   x000D    I added the android exported true and the activity configuration looked like this    x000D   x000D    lt activity x000D          android name   MainActivity  x000D          android exported  true  x000D          android label   string app name  x000D          android configChanges  keyboard keyboardHidden orientation screenSize  x000D          android windowSoftInputMode  adjustResize   gt  x000D         lt activity android name  com facebook react devsupport DevSettingsActivity    gt  x000D      x000D   x000D   x000D

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         lt configuration default  false  name  MyApp  type  AndroidRunConfigurationType  factoryName  Android Application  gt       lt module name  MyApp    gt       lt option name  ACTIVITY CLASS  value  com domain MyApp MyActivity    gt           lt  configuration gt        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

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

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

You need to set android exported  quot true quot  in your AndroidManifest xml file where you declare this Activity   lt activity     android name  quot com example lib MainActivity quot      android label  quot LibMain quot       android exported  quot true quot  gt       lt intent-filter gt           lt action android name  quot android intent action MAIN quot   gt           lt  action gt       lt  intent-filter gt   lt  activity gt
