Android code to run the simple method of specifying APK _android

Sometimes, when we write our own application, we need to implement the specified APK by code, install the specified topic, or install a new apk. You can do this in the following ways:

Copy Code code as follows:

private void installapk (String apkurl) {
Intent Intent = new Intent (Intent.action_view);
Intent.setdataandtype (Uri.parse ("file://" + Apkurl),
"Application/vnd.android.package-archive");
StartActivity (intent);//install
}

Apkurl refers to the path of the application, using intent to open apk for installation.
