1 . 基于Android7.0 有系统签名才能静默安装
直接上代码
下载文件
/**
*下载文件
*这里我是用的子线程
**/
public void DownApkorSysrom( final String loadApkUrl ,final String savePath,final String saveFileName){
Thread thread=new Thread(new Runnable() {
@Override
public void run() {
try {
URL url = new URL(loadApkUrl);
Log.i(TAG,"updateManager download file url:"+loadApkUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.connect();
int length = conn.getContentLength();
InputStream is = conn.getInputStream();
File file;
String filename;
File downFile;
file = new File(savePath);
if (!file.exists()) {
file.mkdir();
}
filename = saveFileName;
downFile = new File(file,filename);
FileOutputStream fos = new FileOutputStream(downFile);
int count = 0;
byte buf[] = new byte[1024];
do {
int numread = is.read(buf);
count += numread;
// 更新进度
int progress = (int) (((float) count / length) * 100);
Log.i(TAG,"down load progress:"+progress+" numread:"+numread);
if (numread <= 0) {
// 下载完成通知安装
apkInstall(savePath+saveFileName);
break;
}
fos.write(buf, 0, numread);
} while (true);// 点击取消就停止下载.
} catch (MalformedURLException e) {
Log.i(TAG,"down load MalformedURLException:"+e.toString());
e.printStackTrace();
} catch (IOException e) {
Log.i(TAG,"down load IOException TTTT:"+e.toString());
e.printStackTrace();
}
}
});
thread.start();
}
2 . 静默安装
/**
* 执行命令并且输出结果
*/
public boolean apkInstall(String path) {
Log.d(TAG,"SilentInstallActivity path:"+path);
Process p=null;
int value=-1;
try {
String docmd = "pm install -r -i com.amtcloud.amtphoneagent --user 0 " +path;
p = Runtime.getRuntime().exec(docmd);
value = p.waitFor();
}catch (Exception e) {
Log.d(TAG, "SilentInstallActivity error: " + e);
}finally {
if(p!=null){
p.destroy();
}
}
return returnResult(value);
}
3 监听安装完成广播
public class SilenceInstallReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// 接收安装广播
if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")||
intent.getAction().equals("android.intent.action.PACKAGE_REPLACED")) {
// startApp("com.amtzhmt.launcher",context);
Toast.makeText(context, "安装完成", Toast.LENGTH_LONG).show();
}
}
public void startApp(String appPackageName,Context context){
try{
Intent intent = context.getPackageManager().getLaunchIntentForPackage(appPackageName);
context.startActivity(intent);
}catch(Exception e){
Toast.makeText(context, "安装完成自启失败", Toast.LENGTH_LONG).show();
}
}
}
