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) {Log.d(TAG, "Examining " + pkg.getPath()+ " and requiring known path " + known.getPathString());}if (!pkg.getPath().equals(known.getPathString())) {throw new PackageManagerException(INSTALL_FAILED_PACKAGE_CHANGED,"Application package " + pkg.getPackageName()+ " found at " + pkg.getPath()+ " but expected at " + known.getPathString()+ "; ignoring.");}} /*else {throw new PackageManagerException(INSTALL_FAILED_INVALID_INSTALL_LOCATION,"Application package " + pkg.getPackageName()+ " not found; ignoring.");}*/}}
