我知道如何在普通Android设备中提取安装的Android应用列表，但是是否可以在Chromebook中获取已安装的Android应用程序列表？
这是我要安装软件包的代码...
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;
}
我将您的代码包裹在活动中：
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，然后我得到了：

所以，您的代码似乎很好。
如果这在您的特定Chrome OS设备上不起作用，则可能会有特定于设备的错误。您可以创建可重现的测试用例并在其上提出问题。
