问题描述
我想要检索的android安装的应用程序列表。我写了下面的code:
I am trying to retrieve the list of installed apps in android. I have written the following code:
final Intent myIntent = new Intent(Intent.ACTION_MAIN, null);
myIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final List AppsList = Context.getPackageManager().queryIntentActivities(myIntent, 0);
我收到此错误:
I am getting this error:
Cannot make a static reference to the non-static method getPackageManager() from the type Context
知道这两个上下文
和 PackageManager
是抽象类,不能纠正错误。请帮助。
Knowing that both Context
and PackageManager
are abstract classes, cannot resolve the error. Kindly help.

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