2 个答案:

答案 0 :(得分：0)

听起来像内存问题或较低版本的兼容性

使用诸如的内存工具 谷歌镀铬内存快照 adb shell dumpsys meminfo com.example.appname

为了兼容性，您可以尝试降低gradle中的sdk版本

答案 1 :(得分：0)

您的应用使用了多少内存？每个设备都有自己的最大允许内存，正在运行的应用程序可以使用您可以使用以下代码行来检查正在运行的特定设备的最大限制。对于旧设备，此数字较低，而较新设备的数字较高，原因显而易见。

Runtime rt = Runtime.getRuntime();
long maxMemory = rt.maxMemory();
Log.i("Android", "maxMemory:" + Long.toString(maxMemory / 1000000) + "Mb");

这将返回您的应用可以使用的最大RAM量，以兆字节为单位。然后，您可以轻松地将此数字与Android Studio中Android Profiler部分中显示的数字进行比较。从那里你应该能够找出问题所在。
