如何在 chromebook 上获取已安装的 android 应用程序包列表？

Question

我知道如何在普通 android 设备中提取已安装的 android 应用程序列表，但是否可以在 chromebook 中获取已安装的 android 应用程序列表？

这是我获取已安装软件包的代码...

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;
}

我将您的代码包装在一个活动中：

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;
  }
}

我在 Acer Chromebook R11 C738T 上运行它，我得到：

所以，你的代码看起来不错。

如果这在您的特定 Chrome 操作系统设备上不起作用，则可能存在特定于设备的错误。 您可以创建一个可重现的测试用例并在其上提出问题。
