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;

3.根据提示修改selinux权限：

avc:  denied  { read } for  scontext=u:r:system_server:s0 tcontext=u:object_r:sdcardfs:s0 tclass=file permissive=0
System server has no access to read file context u:object_r:sdcardfs:s0 (from path /storage/emulated/0/SU70_1.apk, context u:r:system_server:s0)
