更少的代码解决同样的问题。

String[]转String

来自XXX.java
StringBuffer buffer = newStringBuffer();
String projectionList = null;
if(mProjection != null) {
for(String p : mProjection) {
buffer.append(p);
buffer.append(" ");
}
projectionList = buffer.toString();
}
logDebug("mDataUri: "+ mDataUri + " mProjection: "+ projectionList + " mPrimargyKey: "+ mPrimaryKey);

代码review意见：如果你不介意内容格式的话：建议用Arrays.toString()，这个可以顶替你好多代码。

提交者abandon，重新修改后的代码：

改进后的代码
logDebug("mDataUri: "+ mDataUri + " mProjection: "+ Arrays.toString(mProjection) + " mPrima
rgyKey: " + mPrimaryKey);
