I am getting well on with Fedora now. However when I was a fresher to Fedora, I have met a lot of problems.
One of them is that When I type some wrong commands It will take too long to respond. It’s totally different from Ubuntu,which I used before. However I like it could quickly reponse even through the command does not exist.

The fact is that Both my project and my library project which the former refers to have used android-support-v4.jar. However I realize the two android-support-v4.jar are different after making the md5 hash.
My solution:
I use the android-support-v4.jar in my project as the right one. And then replace the one in Facebook SDK with my project one. And then it works.
But my question remains; why it asks me for fix the dependencies to use the same lib jar file?
I guess android will keep only one file for all the references so this will ask developers to make all the same lib all the same.
Sorry for the codeless post.
This will work if you want to remove account without factory reset your device.
When I create a new application on Facebook, I meet the problem. Facebook asks me to provide the Key Hash. But it does not show the guidance about how to generate. After Googling, I have found this works for me.

Replace your-alias-value and your-keystore-path with the real data.
Best answer to the question
Use PRAGMA table_info
This pragma returns one row for each column in the named table. Columns in the result set include the column name, data type, whether or not the column can be NULL, and the default value for the column. The “pk” column in the result set is zero for columns that are not part of the primary key, and is the index of the column in the primary key for columns that are part of the primary key.
