Question

我正在尝试将Halo移植到Cyanogenmod 11.我的设备是xhdpi。构建很顺利，它甚至可以启动，但是使用此日志导致systemui崩溃 - >

W/ActivityManager(  662): Process com.android.systemui has crashed too many times: killing!

在文件“BaseStatusBar.java”中，第472行引用了这部分代码：

protected void updateHalo() {
    mHaloActive = Settings.System.getInt(mContext.getContentResolver(),
            Settings.System.HALO_ACTIVE, 0) == 1;

  //THE LINE BELOW IS LINE 472
    mHaloButton.setImageResource(mHaloActive ? R.drawable.ic_notify_halo_pressed : R.drawable.ic_notify_halo_normal);

    if (mHaloActive) {
        if (mHalo == null) {
            LayoutInflater inflater = (LayoutInflater) mContext
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            mHalo = (Halo) inflater.inflate(R.layout.halo_trigger, null);
            mHalo.setLayerType(View.LAYER_TYPE_HARDWARE, null);
            WindowManager.LayoutParams params = mHalo.getWMParams();
            mWindowManager.addView(mHalo, params);
            mHalo.setStatusBar(this);
        }
    } else {
        if (mHalo != null) {
            mHalo.cleanUp();
            mWindowManager.removeView(mHalo);
            mHalo = null;
        }
    }
}

根据这一点，我认为资源（即图标）“ic_notify_halo_pressed”和“ic_notify_halo_normal”“应该出现在drawable-xhdpi文件夹中吗？是的，它们是。但它仍然会出错。

此外，ic_notify_halo.xml（在drawable文件夹中）具有以下内容 - ＆gt;

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
        android:drawable="@drawable/ic_notify_halo_pressed" />
    <item android:drawable="@drawable/ic_notify_halo_normal" />
</selector>

如果你想看看BaseStatusBar.java-＆gt; http://pastebin.com/nTp2a0wX

我真的无法找到问题，请帮助。

另一件事，在编译/构建rom之前，编译器给了我这个错误 - ＆gt;

frameworks/base/packages/SystemUI/src/com/android/systemui/statusbar/BaseStatusBar.java:1270: cannot find symbol
symbol  : class Resources
location: class com.android.systemui.statusbar.BaseStatusBar
        Resources res = mContext.getResources();
        ^

但是我通过添加导入行来修复它 - ＆gt; import android.content.res.Resources;（这只是猜测，但编译器并没有给我任何错误）。我希望这与问题无关。

找不到可绘制资源，但存在
