解决方法

在android P以前可以使用pm install安装apk，但是在android P出现报以上错误，有以下两种解决方法

1. 将文件拷贝到/data/local/tmp/下再进行安装
   String path = “/data/local/tmp/”;
   String fileName = PathData.utfApkName;
   File apkFile = new File(path + fileName);
   String command = "pm install " + apkFile.getAbsolutePath();
2. 使用cat $apkfile.apk | pm install -S $apkfile.length
   String installCommand = " cat " + apkFile.getAbsolutePath() + " | pm install -S "+ apkLength;
