Android Basic Fragment Example

A dangerous app creates a permission for activities to launch it.

Another app indicates that it requires that permission and then launches it via implicit event.

Also loading browser bookmarks with a different permission from the browser.

Compile

# Optional
ANDROID_HOME=/home/.../android/sdk; export ANDROID_HOME

./gradlew compileDebug

Test

# Make sure emulator is running or connected to real device
./gradlew connectedInstrumentTest

Code highlights

In the AndroidManifest.xml of the DangerousActivity add the permission required to launch it

<!--
      TODO - Using a permission element,
      define a custom permission with name
		  "course.labs.permissions.DANGEROUS_ACTIVITY_PERM"
      and "dangerous" protection level.
-->
<permission android:description="@string/permission_description"
       android:label="string resource"
        android:name="course.labs.permissions.DANGEROUS_ACTIVITY_PERM"
        android:protectionLevel="dangerous" />

Say the activity will respond to implicit event DANGEROUS_ACTIVITY

<activity
    android:name=".DangerousActivity"
    android:label="@string/app_name" >

    <!--
         TODO - add additional intent filter info so that this Activity
          will respond to an Implicit Intent with the action
          "course.labs.permissions.DANGEROUS_ACTIVITY"
    -->
    <intent-filter>
        <action android:name="course.labs.permissions.DANGEROUS_ACTIVITY" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>

The application calling the dangerous activity must require permission in the AndroidManifest.xml

<!-- TODO - add uses-permission elements -->
<uses-permission android:name="course.labs.permissions.DANGEROUS_ACTIVITY_PERM" />
<uses-permission android:name="com.android.browser.permission.READ_HISTORY_BOOKMARKS" />
