Android编程之软件的安装和卸载方法

本文实例讲述了Android编程之软件的安装和卸载方法。分享给大家供大家参考，具体如下：

安装：从sdcard

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);

安装或升级 从网络

Intent intent = new Intent();
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setAction(android.content.Intent.ACTION_VIEW);
/* 调用getMIMEType()来取得MimeType */
String type = getMIMEType(f);
/* 设置intent的file与MimeType */
intent.setDataAndType(Uri.fromFile(f),type);
startActivity(intent);

需要的权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.INSTALL_PACKAGES"></uses-permission>
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

卸载

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

希望本文所述对大家Android程序设计有所帮助。
