易采站长站为您分析Android编程之软件的安装和卸载方法,涉及Android编程实现软件的安装、权限修改及卸载的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了Android编程之软件的安装和卸载方法。，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);
