小编Cuo*_*yen的帖子

在一些帖子请求中,我不知道何时使用@Field,何时使用@Body.像什么是区别:

@POST("users/register")
    Call<String> register(@Body RequestBody registerRequest);

和:

@POST("users/register")
    Call<String> register(@Field String id, @Field String pass);

我可以使用@Body而不是@Field来反转吗？如果没有,为什么？如何知道这个案例使用@Body,其他案例使用@Field？

能否请你给我一些案例并解释一下,谢谢.

我只需通过Tweet分享图片.

这是我的代码

Intent shareIntent = new Intent(Intent.ACTION_SEND);
        shareIntent.setType("image/*");
        if (mInsertableToGallery) {
            mInsertableToGallery = false;
            mInsertedImagePath = MediaStore.Images.Media.insertImage(getContentResolver(), mShareImage,
                    getResources().getString(R.string.app_name) + System.currentTimeMillis(), getResources().getString(R.string.app_name));
        }
        // share only 5 specific apps:
        List<Intent> targetedShareIntents = new ArrayList<>();
        List<ResolveInfo> resInfos = getPackageManager().queryIntentActivities(shareIntent, 0);
        if (!resInfos.isEmpty()) {
            for (ResolveInfo resolveInfo : resInfos) {
                String packageName = resolveInfo.activityInfo.packageName;
                Intent targetedShareIntent = new Intent(Intent.ACTION_SEND);
                targetedShareIntent.setType("image/*");
                targetedShareIntent.setPackage(packageName);
                targetedShareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(mInsertedImagePath));
                if (TextUtils.equals(packageName, "com.facebook.katana") //fb
                ||TextUtils.equals(packageName, "com.instagram.android") //instagram
                ||TextUtils.equals(packageName, "jp.naver.line.android") //line
                ||TextUtils.equals(packageName, "com.google.android.apps.plus") // plus
                ||TextUtils.equals(packageName, "com.twitter.android")) // twitter
            { …

我这样实现:

public static void setPushSetting(Context context, boolean flag) {
    if(flag) {
        FirebaseInstanceId.getInstance().getToken();
    } else {
        try {
            FirebaseInstanceId.getInstance().deleteInstanceId();
        } catch (IOException e) {
            RxBus.getInstance().post(new OffPushError());
            e.printStackTrace();
        }
    }
}

昨天,它有效,但今天FirebaseInstanceId.getInstance().deleteInstanceId();总是抛出异常.

在禁用和启用Firebase推送通知时是否还有其他方法可以实施？谢谢你的帮助!
