如何獲取chromebook上已安裝的android應用程序包列表？

Question

我知道如何從普通的android設備中提取已安裝的android應用程序列表，但是有可能在chromebook中獲取已安裝的android應用程序列表？

這裏是我的代碼來獲取安裝包...

public static List<String> getInstalledAppsPackages(Context context) { 
    List<String> packages = new ArrayList<>(); 
    List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(0); 
    for (int i = 0; i < packs.size(); i++) { 
      PackageInfo packageInfo = packs.get(i); 
      packages.add(packageInfo.packageName); 
     } 
    } 
    return packages; 
} 

Answer 1

我包裹在一個活動代碼：

package com.commonsware.myapplication; 

import android.app.Activity; 
import android.content.Context; 
import android.content.pm.PackageInfo; 
import android.os.Bundle; 
import android.util.Log; 
import java.util.ArrayList; 
import java.util.List; 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    for (String s : getInstalledAppsPackages(this)) { 
     Log.e("20171004", s); 
    } 
    } 

    public static List<String> getInstalledAppsPackages(Context context) { 
    List<String> packages = new ArrayList<>(); 
    List<PackageInfo> packs = context.getPackageManager().getInstalledPackages(0); 
    for (int i = 0; i < packs.size(); i++) { 
     PackageInfo packageInfo = packs.get(i); 
     packages.add(packageInfo.packageName); 
    } 

    return packages; 
    } 
} 

我跑它的宏碁Chromebook R11 C738T，和我：

所以，你的代碼似乎很好。

如果這不適用於您的特定Chrome操作系統設備，則可能存在設備特定的錯誤。您可以創建一個可重複的測試用例並在其上提出問題。
