很多的人可能会对android的安装和下载不太了解,下面我就来给大家做个介绍:
代码如下:
- 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
Java代码
- 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
Java代码
- <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
Java代码
- Uri packageURI = Uri.parse("package:com.android.myapp");
- Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
- startActivity(uninstallIntent);
