lz好，为什么在onSuccess回调里new 一个AlertDialog.Builder来创建对话框时，app就会奔溃呢？log也没有什么提示。代码如下： OkGo.get(ConstantValue.UPDATE_CHECK_URL)
.tag(this)
.params("Platform_type", 1)
.params("OS", "Android7.0")
.execute(new StringCallback() {
@Override
public void onSuccess(Response response) {
//创建对话框
AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
builder.setTitle("版本升级").
setIcon(R.mipmap.ic_launcher).
setMessage("发现新版本！请及时更新").
setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
ToastUtil.showToast(getApplicationContext(), "开始下载。。。。");
}
}).setNegativeButton("取消", null);
AlertDialog alertDialog = builder.create();
alertDialog.show();
