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。
