android - 如何打开 android 内置的下载应用程序？

Question

所以我正在下载东西，它被放入内置的下载应用程序中，因为这就是下载管理器的工作方式。我只想让用户点击一个按钮，打开内置的下载应用程序。这是我的尝试:

btnDownloads.setOnClickListener(new Button.OnClickListener(){
    public void onClick(View v) {
        PackageManager pakMan=MainActivity.context.getPackageManager();
        Log.d("bebr", "Making pak");
        if(pakMan!=null){
            Intent downloadsIntent=new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.android.downloads","com.android.downlods.Downloads"));
            ResolveInfo resolved=pakMan.resolveActivity(downloadsIntent, PackageManager.MATCH_DEFAULT_ONLY);
            Log.d("bebr","Resolving");
            if(resolved!=null){
                Log.d("bebr", "Starting");
                startActivity(downloadsIntent);
            }
        }
    }
});

Ok 终于设法得到解决方案:

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
startActivity(LaunchIntent);

使用 DownloadManager.ACTION_VIEW_DOWNLOADS常量:

startActivity(new Intent(DownloadManager.ACTION_VIEW_DOWNLOADS));
