Error when reading large file on Android

[mannok]

I am trying to read 2xxmb crypt12 file from FS. When I trying to run await RNFS.readFile(${RNFS.ExternalStorageDirectoryPath}/Whatsapp/Databases/msgstore.db.crypt12), it prompts up

Could not invoke RNFSManager.readFile

null

Failed to allocate a 536870928 byte allocation with 25165824 free bytes and 248MB until OOM, max allowed footprint 301365936, growth limit 536870912

I have already set android:hardwareAccelerated="false" and android:largeHeap="true" in AndroidManifest.xml but no luck.

How can I solve it? Thank you

Well, such things happen when you are blowing your devices memory with such a big file. It was never a good practice to load a file completely into memory. You should treat this instead on a chunk-by-chunk basis. Best thing here would be to find a library, that is capable of decrypting the crypt12-file. Then you can load this database (assuming it is Sqlite3 based) with react-native-sqlite-storage to dig trough the data.

There is little chance, that whatsapp is using sqlite-cipher for encyrption (DYOR pls). Then this issue should give you help: https://github.com/craftzdog/react-native-sqlite-2/issues/32

I have tried rn-fetch-blob library instead and it work for me

RNFetchBlob.fs.readStream?

[lyudad]

no const data = RNFetchBlob.wrap(localPath) RNFetchBlob.fetch('POST', url, { 'Content-Type': 'multipart/form-data' }, [ { name: 'file', filename: 'test', data, type: this.mediaMimeType } ]) but I have found that it's slower than send data in base64. So I still looking for faster solution

Getting same error. Device is fresh android emulator with android 11, lots of free space and 800mb free memory so that shouldn't be problem. Error doesn't happen everytime tho, with small files never, ~10mb file, sometimes/often, bigger than that, always.

Same issue here. I am using the read() method to chunk 5Mb segments of a 1Gb file and can process about 300Mb before this fails.

still facing a similar issue when using RNFS.read with a reasonable chunk size, it looks like it tried to allocate memory larger than the chunk size requested.
