android-檢查郵件客戶端裝在設備

檢查郵件客戶端裝在設備

我寫了一段代碼檢查郵件客戶端裝在設備上沒有，但是沒實現，我的代碼：

public boolean isIntentAvailable() {
final PackageManager packageManager = getApplicationContext().getPackageManager();
final Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, "[email protected]");
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.GET_META_DATA);
return list.size() > 0;

}

最佳回答：

我用下面的代碼實現過。試試

public static boolean isMailClientPresent(Context context){
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
final PackageManager packageManager = context.getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, 0);

if(list.size() == 0)
    return false;
else 
    return true;

}
