String fileName = Environment.getExternalStorageDirectory() + "/myApp.apk";           Intent intent = new Intent(Intent.ACTION_VIEW);        intent.setDataAndType(Uri.parse("file://" + filePath),"application/vnd.android.package-archive");        或者        //intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive");         startActivity(intent);

Uri packageURI = Uri.parse("package:com.android.myapp");           Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);           startActivity(uninstallIntent);
