启动应用程序包名称

PackageManager 和 getLaunchIntentForPackage()

只需使用以下两行代码,就可以启动任何已安装的应用程序 package name

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.example.abc");
startActivity( launchIntent );

如果您不知道要启动的应用程序的包名,请尝试使用

PackageManager pm;
pm = getPackageManager();
//  get a list of installed apps.
packages = pm.getInstalledApplications(0);

PackageManager 班级:

PackageManager pm = context.getPackageManager();
Intent launchIntent = pm.getLaunchIntentForPackage("com.example.package");
context.startActivity(launchIntent);

请注意 getLaunchIntentForPackage

if (launchIntent != null) {
    context.startActivity(launchIntent);
} else {
    Toast.makeText(context, "Package not found", Toast.LENGTH_SHORT).show();
}

Intent intent;                                        
PackageManager pm = getActivity().getPackageManager();

intent = pm.getLaunchIntentForPackage("com.package.name");                       
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

startActivity(intent);
