Android开发Error（建议收藏下来以备不时之需）android.os.TransactionTooLargeException: data parcel size xxxx bytes...

前言

该异常触发的概率不大，很多Android猴子可能都没遇到过
但是真的出现的时候别不知道怎么解决

什么情况出现

界面跳转 intent 中的数据内容较多
Android调用系统裁减图片
批量插入大量数据到数据库（我是这种情况，一下主要针对批量插入数据库讲解）

系统源码

源码位置：android/frameworks/base/core/jni/android_util_Binder.cpp
是的你没看错，在以上三种传输中 大于200K就会报错

case FAILED_TRANSACTION: {
            ALOGE("!!! FAILED BINDER TRANSACTION !!!  (parcel size = %d)", parcelSize);
            const char* exceptionToThrow;
            char msg[128];
            // TransactionTooLargeException is a checked exception, only throw from certain methods.
            // FIXME: Transaction too large is the most common reason for FAILED_TRANSACTION
            //        but it is not the only one.  The Binder driver can return BR_FAILED_REPLY
            //        for other reasons also, such as if the transaction is malformed or
            //        refers to an FD that has been closed.  We should change the driver
            //        to enable us to distinguish these cases in the future.
            if (canThrowRemoteException && parcelSize > 200*1024) {    --------- 在这里是有判断的  
                // bona fide large payload
                exceptionToThrow = "android/os/TransactionTooLargeException";
                snprintf(msg, sizeof(msg)-1, "data parcel size %d bytes", parcelSize);
            } else {
                // Heuristic: a payload smaller than this threshold "shouldn't" be too
                // big, so it's probably some other, more subtle problem.  In practice
                // it seems to always mean that the remote process died while the binder
                // transaction was already in flight.
                exceptionToThrow = (canThrowRemoteException)
                        ? "android/os/DeadObjectException"
                        : "java/lang/RuntimeException";
                snprintf(msg, sizeof(msg)-1,
                        "Transaction failed on small parcel; remote process probably died");
            }
            jniThrowException(env, exceptionToThrow, msg);
        } break;

解决方案

intent 传递的数据过大 把大型的序列化集合或者Bitmap缓存 传递缓存路径即可
Android调用系统裁减图片 Bitmap 过大 这个时候只能通过MediaStore.EXTRA_OUTPUT设置裁减图片保存位置，只传递图片路径，不直接传bitmap对象。
批量插入大量数据到数据库 改成分多批 根据自己实际数据量 去衡量每次批量传入多少合适 比如要批量传入100000条数据 每张表的数据还特别多 可以以500条为一批 按批插入
