I would like to show the launcher chooser dialog only on a custom button click and disable it by default. To disable it by default I added an activity alias disabled component inside my app manifest. The alias component has the category 'DEFAULT' inside intent filter declaration.
AndroidManifest.xml
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity-alias
android:enabled="false"
android:name=".DefaultActivity"
android:targetActivity=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.categrory.DEFAULT"/>
</intent-filter>
</activity-alias>
On custom button click the disabled component is enabled:
fun resetDefault() {
val packageManager: PackageManager? = fragment.activity?.packageManager
val compName = fragment.activity?.packageName?.let {
ComponentName(
it,
"$it.DefaultActivity"
)
}
if (compName != null) {
packageManager?.setComponentEnabledSetting(
compName,
PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
PackageManager.DONT_KILL_APP
)
}
val selector = Intent(Intent.ACTION_MAIN)
selector.addCategory(Intent.CATEGORY_HOME)
selector.flags = Intent.FLAG_ACTIVITY_NEW_TASK
fragment.activity?.startActivity(selector)
compName?.let {
packageManager?.setComponentEnabledSetting(
it,
PackageManager.COMPONENT_ENABLED_STATE_DEFAULT,
PackageManager.DONT_KILL_APP
)
}
}
The problem is that the launcher chooser dialog is not showing up and the application is closed insteed. Could anyone tell me what is missing from the current implementation?
