如何以编程方式启动Android应用程序信息屏幕？

Question

是否有可能启动"应用程序信息"屏幕(即Menu→ Settings→ Applications→ Manage Applications从另一个应用程序→选择任何应用程序)？

Answer 1

在2.2及以下版本中,您无法访问公共API.但您仍然可以像ManageApplications那样启动InstalledAppDetails活动.看到这里

 // 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);
 }

结论:您可以像我写的那样启动"应用程序信息"屏幕:

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

从API Level 9(Android 2.3)开始,您可以使用android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS启动Intent .从而:

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);

}

老问题,改进答案:

/**
 * <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

我使用Paolo解决方案,以便在用户过去拒绝权限请求时打开SDK 23+中的应用程序详细信息设置,并在权限请求系统对话框中选择"不再询问"选项.

但在这种情况下,我getPackageName()直接使用了该方法.

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

Answer 5

在Android 2.3的,你可以使用startActivity()上,有一个正确的,把你的应用程序的"管理"屏幕.但是,这是Android 2.3的新功能 - 我不知道在以前版本的Android中有这样做的方法.ACTION_APPLICATION_DETAILS_SETTINGS IntentUri

Answer 6

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

将带您进入设置/应用程序列表.如果你想打开一个特定的应用程序,我想在2.2及以下没有办法,所以你需要去一个(不一定是建议的,因为非官方的)方式:

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);

但请注意,不建议这样做,因为它不是官方的API /意图(过滤器),因此可能会在将来发生变化.
