Android : how to create componentName in code using <activity-alias>

android, android-activity, components

Solution

I have found the solution using this code

String packageName = getPackageName();
try {
    PackageInfo p = getApplicationContext().getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
    for (ActivityInfo activityInfo : p.activities) {
        if(log.d()) log.d("ACT " + activityInfo.name+" "+activityInfo.packageName);
    }
} catch (PackageManager.NameNotFoundException e) {
    e.printStackTrace();
}

if your alias is "alias"

ComponentName componentWithoutTextFiles = new ComponentName(packageName, packageName".alias");

Problem

I have a feature that I only want to be available only when certain conditions are met so I have this activity alias: ``` <activity-alias android:name="share-files-text" android:targetActivity=".MyActivity" android:exported="true" android:enabled="false"> <intent-filter android:label="@string/open_with"> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:mimeType="application/pdf" /> <data android:mimeType="image/*" /> <data android:mimeType="text/plain" /> </intent-filter> </activity-alias> ``` Once in activity I have this code to enable the component ``` String packageName = getPackageName(); ComponentName componentWithTextFiles = new ComponentName(packageName, "share-files-text"); ComponentName componentWithoutTextFiles = new ComponentName(packageName, "share-files"); if(DebugAndTestSettings.ENABLE_TEXT_SLIDE){ getPackageManager().setComponentEnabledSetting(componentWithTextFiles, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 0); getPackageManager().setComponentEnabledSetting(componentWithoutTextFiles, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0); } else { getPackageManager().setComponentEnabledSetting(componentWithTextFiles, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 0); getPackageManager().setComponentEnabledSetting(componentWithoutTextFiles, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 0); } ``` The problem is it crashes saying the package blabla doesn't contain an activity named share-files-text, how can disable/enable this element suing the alias name? Thanks EDIT: I got the idea from this post: Android: Can I enable/disable an activity's intent filter programmatically?
