How to get a list of installed android applications and pick one to run

안드로이드에서 어떻게 설치된 애플리케이션 목록을 가져와서 실행할 애플리케이션을 선택할 수 있나요?

 문제 내용 

I asked a similar question to this earlier this week but I'm still not understanding how to get a list of all installed applications and then pick one to run.

이번 주에 비슷한 질문을 한 적이 있었는데, 아직도 모든 설치된 애플리케이션의 목록을 가져와서 실행할 애플리케이션을 선택하는 방법을 이해하지 못하고 있습니다.

 

I've tried:

제가 시도해본 것은 다음과 같습니다:

Intent intent = new Intent(ACTION_MAIN);
intent.addCategory(CATEGORY_LAUNCHER);

 

and this only shows application that are preinstalled or can run the ACTION_MAIN Intent type.

이렇게 시도해봤는데, 이렇게 하면 미리 설치되어 있는 애플리케이션 또는 ACTION_MAIN Intent 유형을 실행할 수 있는 애플리케이션만 표시됩니다.

 

I also know I can use PackageManager to get all the installed applications, but how do I use this to run a specific application?

또한 PackageManager를 사용하여 설치된 모든 응용 프로그램을 가져올 수 있다는 것도 알고 있지만 특정 응용 프로그램을 실행하기 위해 이를 어떻게 사용해야 하나요?

Here's a cleaner way using the PackageManager

PackageManager를 사용하는 더 깔끔한 방법이 있습니다.

final PackageManager pm = getPackageManager();
//get a list of installed apps.
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo packageInfo : packages) {
    Log.d(TAG, "Installed package :" + packageInfo.packageName);
    Log.d(TAG, "Source dir : " + packageInfo.sourceDir);
    Log.d(TAG, "Launch Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName)); 
}
// the getLaunchIntentForPackage returns an intent that you can use with startActivity()

This answer is correct an list of installed app show and search feature add.

이 답변은 정확합니다. 설치된 앱 목록이 나열되며 검색 기능이 추가되었습니다.
