android安装root,android开发实现静默安装（root权限）
⽅式是将应⽤设置为内置的系统应⽤，注意事system/app⽬录下⾯，采⽤copy2SystemApp()⽅法就可以，注意chmod 777的权限，若是直接将apk拷贝到system/app⽬录，没有这个权限还是不能静默安装的。
直接贴出⼯具类：
public class ApkController {
/**
* 描述: 安装
*/
public static boolean install(String apkPath,Context context){
// 先判断⼿机是否有root权限
if(hasRootPerssion()){
// 有root权限，利⽤静默安装实现
return clientInstall(apkPath);
}else{
// 没有root权限，利⽤意图进⾏安装
File file = new File(apkPath);
if(!ists())
return false;
Intent intent = new Intent();
intent.setAction("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.fromFile(file),"application/vnd.android.package-archive");
context.startActivity(intent);
return true;
}
}
