A wrapper of Android Storage Access Framework for writing files on Ext SD card in both Java and JNI native code.
Use DocumentFile for Java code to write,
and xhook to hook native code (such as fopen, mkdir, remove),
so that the native code can use SAF to write file.
See `SafFile.java' in detail.
- Use
requestDocUri
to get thedocUri
, and usesaveDocUriFromResult
inonActivityResult
to save thedocUri
inSharedPreference
- You can write the file on EXT sdcard by
writeFileSaf
as well as the other Saf fucntions.
- Use
build.cmd
to buildlibyurihook.so
, then putlibyurihook.so
andlibxhook.so
to your app's lib - Load the
libyurihook.so
in your app - Use
nativeInitSafJavaCallbacks()
andnativeHookFile(String hooksoStr, String soPath)
for jni file hook.
hooksoStr
, which passed toxhook_register
, can use regex to match the hooked path(all of them are hooked), such as ".*\.so$"
soPath
, if not null, it will dlopen that path before hook
