Question

public final class ProgressWidget extends LinearLayout {

    <Default Constructors implemented> {
        setOrientation(LinearLayout.VERTICAL);
        inflate(context, R.layout.horizontal_progress, this);
    }

    @Override
    protected void onFinishInflate() {
        //Continue with rest of the logic.
    }
}

R.layout.horizontal_progress有35行。

一切正常在手机设备上 - 三星Galaxy S5 SM-G900A，Android 5.0版。在Asus Nexus 7，Android 4.4.3上始终与上面的堆栈跟踪崩溃。

此ProgressWidget是Android库模块的自定义可重用组件，将与项目模块一起使用。主要的项目模块预计将迎合minSDKVersion 16一直到TargetSDKVersion 24。

任何有关可能导致平板电脑设备崩溃的指示都将非常感激。

Answer 1

尝试更改最后一个渐变（具有tools:ignore="NewApi"行的渐变）中的颜色。这两种颜色未在SDK＆lt; 21中定义。如果这还没有解决，请发布更多的堆栈跟踪。
