备注：

public static String getBuildInfo() { // minimal info for 1.5 support
		final String buildInfo = String.format("AndroidVersion= %s Product= %s ID= %s Model= %s",
				android.os.Build.VERSION.RELEASE, android.os.Build.PRODUCT, android.os.Build.ID, android.os.Build.MODEL);
		return buildInfo;
	}

注意这种格式化输出信息
