How to determine whether a program is installed on your phone?

This article describes the method of Android programming to determine whether a program is installed on your phone. Share it for your reference, as follows:

1. First get the package name of the program

Connect this to your mobile phone ADB and you can see it by looking at logcat. For example: The package name of the QQ client is.

2. Then use the PackageManager to determine whether the package's program exists.

private boolean isPkgInstalled(String pkgName) {
PackageInfo packageInfo = null;
try {
  packageInfo = ().getPackageInfo(pkgName, 0);
} catch (NameNotFoundException e) {
  packageInfo = null;
  ();
}
if (packageInfo == null) {
  return false;
} else {
  return true;
}

I hope this article will be helpful to everyone's Android programming design.
