通过包名进入指定程序的卸载activity

private void unstallApp(PackageInfo packageInfo) {
Uri packageuri = Uri.parse("package:"+ packageInfo.packageName);//获取指定包名的uri
Intent deleteintent = new Intent();//创建intent对象
deleteintent.setAction(Intent.ACTION_DELETE);//设置这个intent要做的动作
deleteintent.setData(packageuri);//将URI和intent结合起来
startActivity(deleteintent);
}
