android - 无法对非静态方法 getPackageManager() 进行静态引用

Question

我正在尝试检索 android 中已安装应用程序的列表。我写了下面的代码:

final Intent myIntent = new Intent(Intent.ACTION_MAIN, null);
myIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List AppsList = Context.getPackageManager().queryIntentActivities(myIntent, 0);

我收到这个错误:

Cannot make a static reference to the non-static method getPackageManager() from the type Context

知道Context和PackageManager都是抽象类，无法解决错误。请帮忙。

尝试:

final List AppsList = getApplicationContext().getPackageManager().queryIntentActivities(myIntent, 0);
