android studio 64位手機+Fresco引起的在arm64位機器上找不到對應的so庫

我們的程序在32位機器上沒有問題，有一天公司采購了一臺魅族MX5

MTK的64位處理器上我們的應用報錯了

"nativeLibraryDirectories=[/data/app/com.lukouapp-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find"libxxxx.so"

仔細排查后發現是因為使用了Fresco

通過排查fresco的issue-關于64bit的問題發現

Issue#504

Issue#458

問題原因：64位機器默認去查找arm64-v8a目錄下是否有合適的64位庫，如果沒有則回去libs下查找32位的庫，而fresco的draw-pipeline太完善了考慮了64位的機器所以他的arm64-v8a下有so庫，

對應的系統就創建了lib64的文件，而不再去找32位的庫。

解決方案：

Edit your build.gradle fileasfollows:

android {//rest of your app's logicsplits {

abi {

enabletruereset()

include'x86','x86_64','arm64-v8a','armeabi-v7a','armeabi'universalApkfalse} ?}}

(*)注意上面的紅色部分要刪除掉最后看起來是這樣：

android {//rest of your app's logicsplits {

abi {

enabletruereset()

include'x86','x86_64','armeabi-v7a','armeabi'universalApkfalse}

}

}

原理：

enable: enables the ABIs split mechanism

exclude: By default all ABIs are included, you can remove some ABIs.

include: indicate which ABIs to be included

reset(): reset the list of ABIs to be included to an empty string (this allows, in conjunctions withinclude, to indicate which one to use rather than which ones to ignore)

universalApk: indicates whether to package a universal version (with all ABIs) or not. Default is false.

注意：如果加入上面代碼還不行 ，可以注釋掉下面這行（如果你的主要工程目錄沒有加入lib和jar的話）

dependencies {//compile fileTree(include: ['*.jar'], dir: 'libs')}

以上方法發現并沒有解決，采用以下的方法解決的最后

down voteIf you have only x86 and armeabi-v7a libraries, your app should automatically be installed in "32-bit mode".

Try to use this in your gradle file:

android { .... defaultConfig { .... ndk { abiFilters "armeabi-v7a", "x86" } } }
