How can I start android application info screen programmatically?

Question

是否可以从另一个应用程序启动“应用程序信息”屏幕（即Menu → Settings → Applications → Manage Applications →选择任何应用程序）？

Answer 1

In 2.2 and below, there is no public APIs you can access. But you can still start the InstalledAppDetails activity just as the ManageApplications does. see here

 // utility method used to start sub activity
 private void startApplicationDetailsActivity() {
     // Create intent to start new activity
     Intent intent = new Intent(Intent.ACTION_VIEW);
     intent.setClass(this, InstalledAppDetails.class);
     intent.putExtra(APP_PKG_NAME, mCurrentPkgName);
     // start new activity to display extended information
     startActivityForResult(intent, INSTALLED_APP_DETAILS);
 }

Conclusion : you can start the "application info" screen like this i wrote:

private static final String SCHEME = "package";

private static final String APP_PKG_NAME_21 = "com.android.settings.ApplicationPkgName";

private static final String APP_PKG_NAME_22 = "pkg";

private static final String APP_DETAILS_PACKAGE_NAME = "com.android.settings";

private static final String APP_DETAILS_CLASS_NAME = "com.android.settings.InstalledAppDetails";

public static void showInstalledAppDetails(Context context, String packageName) {
    Intent intent = new Intent();
    final int apiLevel = Build.VERSION.SDK_INT;
    if (apiLevel >= 9) { // above 2.3
        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        Uri uri = Uri.fromParts(SCHEME, packageName, null);
        intent.setData(uri);
    } else { // below 2.3
        final String appPkgName = (apiLevel == 8 ? APP_PKG_NAME_22
                : APP_PKG_NAME_21);
        intent.setAction(Intent.ACTION_VIEW);
        intent.setClassName(APP_DETAILS_PACKAGE_NAME,
                APP_DETAILS_CLASS_NAME);
        intent.putExtra(appPkgName, packageName);
    }
    context.startActivity(intent);
}

Answer 2

From API Level 9 (Android 2.3) you can start an Intent with android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS . Thus:

packageName = "your.package.name.here"

try {
    //Open the specific App Info page:
    Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    intent.setData(Uri.parse("package:" + packageName));
    startActivity(intent);

} catch ( ActivityNotFoundException e ) {
    //e.printStackTrace();

    //Open the generic Apps page:
    Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
    startActivity(intent);

}

Old question, improved answer:

/**
 * <p>Intent to show an applications details page in (Settings) com.android.settings</p>
 * 
 * @param context       The context associated to the application
 * @param packageName   The package name of the application
 * @return the intent to open the application info screen.
 */
public static Intent newAppDetailsIntent(Context context, String packageName) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
        Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setData(Uri.parse("package:" + packageName));
        return intent;
    } else if (Build.VERSION.SDK_INT == Build.VERSION_CODES.FROYO) {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setClassName("com.android.settings",
                "com.android.settings.InstalledAppDetails");
        intent.putExtra("pkg", packageName);
        return intent;
    }
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.setClassName("com.android.settings",
            "com.android.settings.InstalledAppDetails");
    intent.putExtra("com.android.settings.ApplicationPkgName", packageName);
    return intent;
}

Answer 4

I used Paolo solution in order to open the Application Details Settings in SDK 23+ when the user turned down the permission request in the past and choose the "Don't ask again" option in the permission request system dialog.

But in this case I used the getPackageName() method directly.

Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:" + getPackageName()));
startActivity(intent);

Answer 5

In Android 2.3, you can use startActivity() on an ACTION_APPLICATION_DETAILS_SETTINGS Intent , with a proper Uri , to bring up your app's "manage" screen. However, this is new to Android 2.3 -- I am not aware of a way to do that in previous versions of Android.

Answer 6

startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_SETTINGS));

will bring you to the settings / application list. If you want to open one specific application, I think in 2.2 and below there's no way, so you'd need to go a (not necessarily suggested, because inofficial) way:

final Intent i = new Intent("android.intent.action.VIEW");                
i.setComponent(new ComponentName("com.android.settings","com.android.settings.InstalledAppDetails"));
i.putExtra(...); // need to figure out the correct extra, probably app package name
startActivity(i);

But note that this is not recommended because it's not an official API / intent (filter) and might therefore change in the future.
