written for k9  So  i will only be able to include the built-in permissions of android in the above given permissions  I tried by doing so as well  but it didn t solve my issue

You have to add android exported  true  in the manifest file in the activity you are trying to start   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       The default value depends on whether the activity contains intent filters  The absence of any filters means that the activity can be invoked only by specifying its exact class name  This implies that the activity is intended only for application-internal use  since others would not know the class name   So in this case  the default value is  false   On the other hand  the presence of at least one filter implies that the activity is intended for external use  so the default value is  true        This attribute is not the only way to limit an activity s exposure to other applications  You can also use a permission to limit the external entities that can invoke the activity  see the permission attribute

Make sure that the component has the  exported  flag set to true  Also the component defining the permission should be installed before the component that uses it

In your Manifest file write this before  lt  application  gt    lt activity android name  com fsck k9 activity MessageList  gt      lt intent-filter gt         lt action android name  android intent action MAIN  gt         lt  action gt      lt  intent-filter gt   lt  activity gt    and tell me if it solves your issue

The java lang SecurityException you are seeing is because you may enter two entries pointing to the same activity  Remove the second one and you should be good to go   More Explanation  You may be declared the activity 2 times in the manifest with different properties  like      lt activity android name   myclass  gt   lt  activity gt    and     lt activity android name   myclass  android label   string app name  gt         lt intent-filter gt             lt action android name  android intent action MAIN    gt            lt category android name  android intent category LAUNCHER    gt        lt  intent-filter gt    lt  activity gt    You should remove the unwanted one from the manifest

I had this problem with this exact activity   You can t start com fsck k9 activity MessageList from an external activity   I solved it with   Intent LaunchK9   getPackageManager   getLaunchIntentForPackage  com fsck k9    this startActivity LaunchK9    Using http   developer android com reference android content pm PackageManager html

I was running into the same issue and wanted to avoid adding the intent filter as you described   After some digging  I found an xml attribute android exported that you should add to the activity you would like to be called   It is by default set to false if no intent filter added to your activity  but if you do have an intent filter it gets set to true   here is the documentation http   developer android com guide topics manifest activity-element html exported  tl dr  addandroid exported  true  to your activity in your AndroidManifest xml file and avoid adding the intent-filter
