修改步骤与Android11是差不多的，只是有部分代码所在位置不一样。
Android 11®内置APP到data/app
Android 8(O)预置APP到data/app
默认内置应用到data会出错

userdata.img只有几十k的问题
往data中加了几百M大小的app，在out/xx/data/app中也看到编译出来了，
但是编译后却发现userdata.img只有90k，是空的分区，
在.mk中修改userdata分区大小，.mk里面默认是64M， 改成512M解决了。

实现
Android11中修改的是
frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java
Android 13不同，需要修改
frameworks/base/services/core/java/com/android/server/pm/InstallPackageHelper.java
注释掉
else {
throw new PackageManagerException(INSTALL_FAILED_INVALID_INSTALL_LOCATION,
"Application package " + pkg.getPackageName()
+ " not found; ignoring.");
}
完整代码如下
if ((scanFlags & SCAN_REQUIRE_KNOWN) != 0) {
if (mPm.isExpectingBetter(pkg.getPackageName())) {
Slog.w(TAG, "Relax SCAN_REQUIRE_KNOWN requirement for package "
+ pkg.getPackageName());
} else {
PackageSetting known = mPm.mSettings.getPackageLPr(pkg.getPackageName());
if (known != null) {
if (DEBUG_PACKAGE_SCANNING) {
