发布了未知的位图参考 - 在 android 中设置标记

CODE :-

    /**
     * Update marker position and icon
     */
    private void setMarker() {
        synchronized (OBJ_LOCK) {
            if (mLatitude != 0.0 || mLongitude != 0.0) {
                mRotatedBitmap = rotateBitmap(mOriginalMarkerBitmap, mBearing);

                if (mRotatedBitmap != null) {
                    mCurrentPositionIcon = BitmapDescriptorFactory
                            .fromBitmap(mRotatedBitmap);
                    mCurrentLocationMarker.position(new LatLng(mLatitude,
                            mLongitude));

                    mCurrentLocationMarker.icon(mCurrentPositionIcon);
                    mCurrentLocationMarker.anchor(0.5f, 0.5f);

                    if (currentMarker != null && mCurrentPositionIcon != null) {
                        currentMarker.setIcon(mCurrentPositionIcon);
                        currentMarker.setAnchor(0.5f, 0.5f);
                        currentMarker.setPosition(new LatLng(mLatitude,
                                mLongitude));
                    } else {
                        currentMarker = mGoogleMap
                                .addMarker(mCurrentLocationMarker);
                    }
                }
            }
        }
    }

已经检查了#SO发布未知位图参考 https://stackoverflow.com/questions/18097090/released-unknown-bitmap-reference，但对我来说一点帮助都没有。

这对我有用：不要使用死标记引用：currentMarker 可以不为空，但同时可能会引用以前的地图。

当你不需要标记引用时（onDestroy 或 onPause），总是丢弃它们，并且总是获取新的，只是不要仅仅依赖currentMarker!=null

    ...

    if (currentMarker == null)
        currentMarker = mGoogleMap.addMarker(mCurrentLocationMarker);

    if (mCurrentPositionIcon != null) {
        currentMarker.setIcon(mCurrentPositionIcon);
        currentMarker.setAnchor(0.5f, 0.5f);
        currentMarker.setPosition(new LatLng(mLatitude,mLongitude));
    }

    ...

@Override
public void onPause() {
    currentMarker.remove();
    currentMarker = null;
}
