Android Constrain佈局使用太多的內存（RAM）（內存泄漏）

我真的不明白在約束佈局上會發生什麼。Android Constrain佈局使用太多的內存（RAM）（內存泄漏）

我以前的UI使用只有15 MB RAM，同時新的UI使用400MB〜

任何人有一個想法？

舊UI

使用RAM〜15MB的實際Android設備

這似乎是bug是在編譯「com.android.support.constraint：約束的佈局：1.0。 0-alpha4'

新的UI使用的α4但老UI使用素α3

然後我用

compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'

與新UI。 現在錯誤已被固定在alpha7太

有阿爾法4錯誤，得到了在阿爾法6解決這或許可以解釋你所看到的（這顯然是完全不正常的，約束佈局其實應該非常使用小公羊）。你能否檢查一下是否解決了你的問題，如果沒有提交錯誤？謝謝！

另一個答案已經表明，它是通過降級到alpha3 –

修復的。當然，不推薦alpha3使用:-) - 我們發佈alpha4，alpha5和alpha6 ...的原因是...（許多錯誤修復，性能改進和API更改）。具體來說，alpha 4具有很大的內部整體幫助性能，所以知道alpha 3沒有問題是很好的，但是知道alpha 6是否解決了這個問題會更有用 - 它可能會，但是如果這不是我們需要照顧的） –

我已經嘗試了alpha7的固定。 – UmAnusorn
