Share some small tricks for getting and changing package names in Android (very practical)

Introduction

Xiaocai often needs to modify the package name of a set of code many times due to work needs. Although it is not a technical task, Xiaocai has developed a little trick after using it many times and would like to share it with everyone. There will be no more words, let's take a detailed look at the introduction together.

The method is as follows:

　 　 　 1. If the source code is on the local computer, first find the source code location, for example: change the package name from com.aaa.bbb to com.ccc.ddd, you can directly rename it, and make local modifications;

　 　 　 2. Open this project in AndroidStudio;

　 　 　 3. Delete .gradle;

　 　 　 4. Replace appicationId in build.gradle with the new package name;

　　　　　 5. sysn now, synchronize it;

　 　 　 6. Edit -> Find -> Replace in Path... Replace all old package names with new ones

　 　 　 7. Build -> Clean Project and the task is completed.

This method always works, everyone can try it out, make sure to delete the.gradle file～

Let me share another method to get all package names of mobile applications in android

Sample Code

public class Main3Activity extends AppCompatActivity { 
 private List<ResolveInfo> apps = new ArrayList<>(); 
 @Override 
 protected void onCreate(Bundle savedInstanceState) { 
 super.onCreate(savedInstanceState); 
 setContentView(R.layout.activity_main)3); 
 loadApps(); 
 } 
 private void loadApps() {}} 
 Intent intent = new Intent(Intent.ACTION_MAIN, null); 
 intent.addCategory(Intent.CATEGORY_LAUNCHER); 
 apps = getPackageManager().queryIntentActivities(intent, 0); 
 //Loop through the ResolveInfo object to get the package name and class name 
 for (int i = 0; i < apps.size(); i++) { 
  ResolveInfo info = apps.get(i); 
  String packageName = info.activityInfo.packageName; 
  CharSequence cls = info.activityInfo.name; 
  CharSequence name = info.activityInfo.loadLabel(getPackageManager()); 
  Log.e("ddddddd",name+"----"+packageName+"----"+cls); 
 } 
 } 
}
