使用androidx.window时一加、OPPO设备Android13+系统崩溃

在非折叠屏的一加、OPPO设备（仅Android 13及以上系统）中，添加折叠屏识别逻辑后应用出现崩溃。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

        Timber.tag(TAG).d("onStart: isFoldableDevice");
        windowInfoTracker.addWindowLayoutInfoListener(this, Runnable::run, layoutStateChangeCallback);
    }
}

@Override
protected void onStop() {
    super.onStop();
    if (Utilities.isFoldableDevice(this)) {
        windowInfoTracker.removeWindowLayoutInfoListener(layoutStateChangeCallback);
    }
}

class LayoutStateChangeCallback implements Consumer<WindowLayoutInfo> {
    @Override
    public void accept(WindowLayoutInfo newLayoutInfo) {
        EpubReaderActivity.this.runOnUiThread(() -> {
            try {
                boolean isDeviceFlatFoldable = !newLayoutInfo.getDisplayFeatures().isEmpty();
                Timber.tag(TAG).d("accept: isDeviceFlatFoldable = %s", isDeviceFlatFoldable);
                if (preferencesManager.getIsDeviceFlatFoldable() != isDeviceFlatFoldable) {
                    preferencesManager.setIsDeviceFlatFoldable(isDeviceFlatFoldable);
                    EventBus.getDefault().post(new EpubColumnsChangeEvent());
                }
            } catch (Exception e) {
                Timber.e(e);
            }
        });
    }
}

public static boolean isFoldableDevice(Context context) {
    // at least Android 11 (Version code 30) is required
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.R) {
        return context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_SENSOR_HINGE_ANGLE);
    }
    return false;
}

依赖配置 #

implementation 'androidx.window:window-java:1.3.0'

解决方案 #

崩溃原因是androidx.window:window-java:1.3.0版本与一加、OPPO的Android 13+系统存在兼容性问题，系统调用了库中未实现的onDeviceStateChanged抽象方法。可通过以下步骤修复：

1. 升级window库版本
   将依赖升级到最新稳定版（如1.10.0），新版本修复了此类厂商兼容性问题：

   implementation 'androidx.window:window-java:1.10.0'
   

2. 优化折叠屏判断逻辑
   原有仅通过FEATURE_SENSOR_HINGE_ANGLE判断不够全面，结合系统DisplayFeature检测更准确：

   public static boolean isFoldableDevice(Context context) {
       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
           WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
           Display display = wm.getDefaultDisplay();
           DisplayFeature[] features = display.getDisplayFeatures();
           // 检测是否存在折叠或铰链相关的显示特征
           for (DisplayFeature feature : features) {
               if (feature.getType() == DisplayFeature.TYPE_FOLD || feature.getType() == DisplayFeature.TYPE_HINGE) {
                   return true;
               }
           }
           // 回退到传感器判断逻辑
           return context.getPackageManager().hasSystemFeature(PackageManager.FEATURE_SENSOR_HINGE_ANGLE);
       }
       return false;
   }
   

3. 增加初始化及回调的异常防护
   避免初始化WindowInfoTracker时崩溃，同时在生命周期方法中增加空判断：

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_epub_reader);
       try {
           windowInfoTracker = new WindowInfoTrackerCallbackAdapter(WindowInfoTracker.getOrCreate(this));
       } catch (Exception e) {
           Timber.e(e, "Failed to initialize WindowInfoTracker");
           windowInfoTracker = null;
       }
   }
   
   @Override
   protected void onStart() {
       super.onStart();
       if (windowInfoTracker != null && Utilities.isFoldableDevice(this)) {
           Timber.tag(TAG).d("onStart: isFoldableDevice");
           windowInfoTracker.addWindowLayoutInfoListener(this, Runnable::run, layoutStateChangeCallback);
       }
   }
   
   @Override
   protected void onStop() {
       super.onStop();
       if (windowInfoTracker != null && Utilities.isFoldableDevice(this)) {
           windowInfoTracker.removeWindowLayoutInfoListener(layoutStateChangeCallback);
       }
   }
