问题描述

我想禁用某些功能并减少Android Go设备上的内存消耗.我想为所有Android设备安装一个APK.

I'd like to disable some features and reduce memory consumption on Android Go Devices. I'd like to have one APK for all Android devices.

如何检测我的应用程序正在Android Go 8.1设备上运行?是否足以检查版本8.1或将8.1版本也分发到正常的Android设备上?

How do I detect that my app is running on an Android Go 8.1 Device? Is it sufficient to check for version 8.1 or will 8.1 version be distributed to normal Android Devices as well?

推荐答案

这对我有效，基于预先安装的Apps.

This works for me, based on preinstalled Apps.

如果安装了 Assistant Go 或 Google Go 版本，则肯定是Android Go设备.

If Assistant Go or Google Go versions are installed, definitely is an Android Go device.

在极少数情况下，如果没有预先安装这些应用，我们会寻找 Gmail Go 和 Youtube Go .

In rare cases that these apps didn't come preinstalled we look for Gmail Go and also Youtube Go preinstalled.

在带有Android 8.1(Go)的华为Y5 Lite上进行了测试.

Tested on Huawei Y5 Lite with Android 8.1 (Go).

public static boolean isAndroidGoEdition(Context context) {
    final String GMAIL_GO = "com.google.android.gm.lite";
    final String YOUTUBE_GO = "com.google.android.apps.youtube.mango";
    final String GOOGLE_GO = "com.google.android.apps.searchlite";
    final String ASSISTANT_GO = "com.google.android.apps.assistant";

    boolean isGmailGoPreInstalled = isPreInstalledApp(context, GMAIL_GO);
    boolean isYoutubeGoPreInstalled = isPreInstalledApp(context, YOUTUBE_GO);
    boolean isGoogleGoPreInstalled = isPreInstalledApp(context, GOOGLE_GO);
    boolean isAssistantGoPreInstalled = isPreInstalledApp(context, ASSISTANT_GO);

    if(isGoogleGoPreInstalled | isAssistantGoPreInstalled){
        return true;
    }
    if(isGmailGoPreInstalled && isYoutubeGoPreInstalled){
        return true;
    }

    return false;
}

private static boolean isPreInstalledApp(Context context, String packageName){
    try {
        PackageManager pacMan = context.getPackageManager();
        PackageInfo packageInfo = pacMan.getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
        if(packageInfo != null){
            //Check if comes with the image OS
            int mask = ApplicationInfo.FLAG_SYSTEM | ApplicationInfo.FLAG_UPDATED_SYSTEM_APP;
            return (packageInfo.applicationInfo.flags & mask) != 0;
        }
    } catch (PackageManager.NameNotFoundException e) {
        //The app isn't installed
    }
    return false;
}
