android 安装apk包 卸载 包

android apk 安装

String str = "/CanavaCancel.apk"; 
String fileName = Environment.getExternalStorageDirectory() + str; 
Intent intent = new Intent(Intent.ACTION_VIEW); 
intent.setDataAndType(Uri.fromFile(new File(fileName)), "application/vnd.android.package-archive"); 
startActivity(intent);

卸载：
Environment拥有一些可以获取环境变量的方法
package:com.demo.CanavaCancel 这个形式是 package:程序完整的路径 (包名+程序名).

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