Android startet Twitter Intent

Question

Ich verwende den folgenden Code zum Starten von Twitter Absicht, funktioniert aber nicht. Ich habe die Twitter App auf meinem Handy installiert. Brauche Hilfe!

 Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND); 
     shareIntent.setType("text/plain"); 
     shareIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Content to share"); 
     PackageManager pm = contexto.getPackageManager(); 
     List<ResolveInfo> activityList = pm.queryIntentActivities(shareIntent, 0); 
     for (final ResolveInfo app : activityList) { 
      if ("com.twitter.android.PostActivity".equals(app.activityInfo.name)) { 
       final ActivityInfo activity = app.activityInfo; 
       final ComponentName name = new ComponentName(activity.applicationInfo.packageName, activity.name); 
       shareIntent.addCategory(Intent.CATEGORY_LAUNCHER); 
       shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED); 
       shareIntent.setComponent(name); 
       contexto.startActivity(shareIntent); 
       break; 
      } 
     } 

Erste Ausnahme, wenn ich versuche, um die Aktivität zu nennen:

 android.content.ActivityNotFoundException: Unable to find explicit activity class {com.twitter.android/com.twitter.android.PostActivity}; have you declared this activity in your AndroidManifest.xml?

Typischerweise

Intent intent = null; 
try { 
    // get the Twitter app if possible 
    this.getPackageManager().getPackageInfo("com.twitter.android", 0); 
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?user_id=USERID")); 
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
} catch (Exception e) { 
    // no Twitter app, revert to browser 
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/USERID_OR_PROFILENAME")); 
} 
this.startActivity(intent); 

für Post Intent

Intent tweetIntent = new Intent(Intent.ACTION_SEND); 
tweetIntent.putExtra(Intent.EXTRA_TEXT, "This is a Test."); 
tweetIntent.setType("text/plain"); 

PackageManager packManager = getPackageManager(); 
List<ResolveInfo> resolvedInfoList = packManager.queryIntentActivities(tweetIntent, PackageManager.MATCH_DEFAULT_ONLY); 

boolean resolved = false; 
for(ResolveInfo resolveInfo: resolvedInfoList){ 
    if(resolveInfo.activityInfo.packageName.startsWith("com.twitter.android")){ 
     tweetIntent.setClassName(
      resolveInfo.activityInfo.packageName, 
      resolveInfo.activityInfo.name); 
     resolved = true; 
     break; 
    } 
} 
if(resolved){ 
    startActivity(tweetIntent); 
}else{ 
    Toast.makeText(this, "Twitter app isn't found", Toast.LENGTH_LONG).show(); 
}

leicht korrigiert einen Benutzer Futter für den Start (Danke an Taranfx) eine Verwendung r Feed Intent (Änderung user_id =>screen_name):

public static void startTwitter(Context context) { 

    Intent intent = null; 
    try { 
     // get the Twitter app if possible 
     context.getPackageManager().getPackageInfo("com.twitter.android", 0); 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("twitter://user?screen_name=<place_user_name_here>")); 
     intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     return intent; 
    } catch (Exception e) { 
     // no Twitter app, revert to browser 
     intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://twitter.com/<place_user_name_here>")); 
    } 
    startActivity(intent); 
}
