7.0 apk 安装 （pm 命令）

最近在移植rom模块到 7.0 时， 发现之前静默安装的功能无法实现了，会报出错误:

java.lang.SecurityException: runInstallCreate from pm command asks to run as user ….. requires android.permission.INTERACT_ACROSS_USERS_FULL

然后 我就很情愿的按照他的错误， 去我的app 里面加上了这个权限。以为可以成功，加了之后一样错误不行， 然后就百度了一下， 也基本没有发现什么解决方案

相关一些 pm 等的东西，后面再发

那可能之前的安装apk代码都是以下几种：

1.  Process p = Runtime.getRuntime().exec(“pm install -r  apkpath”)
                        p.waitFor();

2.  Process p = Runtime.getRuntime().exec( new String[]{ "pm", "install", "-r", apk})
                        p.waitFor();

3.  private void SilentInstall(Context mContext,final String mypackageName, String path) {
         Uri uri = Uri.fromFile(new File(path));
         //Log.d(TAG, "SilentInstall path="+path);
         //Log.d(TAG, "SilentInstall uri="+uri);
         //Log.d(TAG, "SilentInstall packageName="+packageName);
           int installFlags = 0;
           PackageManager pm = mContext.getPackageManager();
           try {
              PackageInfo packageInfo = pm.getPackageInfo(mypackageName,
                     PackageManager.GET_UNINSTALLED_PACKAGES);
                if (packageInfo != null) {
                   installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;
             }
           } catch (NameNotFoundException e) {
              //Log.e(TAG, "NameNotFoundException = " + e.getMessage());
          }

          pm.installPackage(uri, new IPackageInstallObserver.Stub() {
              @Override
              public void packageInstalled(String packageName, int returnCode) {
              // Looper.prepare();
                  if (returnCode == 1) {
                        Log.d(TAG, "install apk Success packageName:"+ packageName);
                    } else {
                       Log.d(TAG, "install fail!");
                   }
                 // Looper.loop();
                }
          }, installFlags, mypackageName);
     }

然后就去源码查到了一些 7.0 的用法 ，送给遇到问题的小伙伴（用法参数里面都有解释有些是英文）

       pm path [--user USER_ID] PACKAGE          //查看apk安装后位置

       pm dump PACKAGE                           //打印给定的包的系统状态
