今天遇到一個很坑的問題：打包簽名apk出現問題，debug包沒毛病，但是release包卻怎麼也不成功，具體日誌信息如下：

查找了一翻資料，解決方案几乎都是在app的build.gradle下增加如下代碼：
lintOptions {
checkReleaseBuilds false
abortOnError false
}
其他方案可參考：https://blog.csdn.net/wjj1996825/article/details/79838430
最後通過跟蹤stacktrace信息發現是png問題 = =，貌似是我當初爲了方便，直接將jpeg格式的圖片後綴修改爲了png，結果內部文件格式並沒有變，導致release打包檢查的時候報錯。
OK，還get了一個過濾無關錯誤信息的小技巧：
嗯，雖然不是什麼大問題，但真正查找起來還挺麻煩，權當記錄一下。
