Android DDMS connection to the real machine (root), with file explore to see the Data/data folder solutionThe problem is no permission, with 360 mobile phone helper or pea pod is also invisible. The easy way is to use the RE File manager (grant root permission), set data and Data/data to 777 permissionsNote: Open with the RE manager to see the default is not 777,
In Android development, if you use a database to store data, it is inevitable to look at the contents of the database, but for the root of the real machine, it is not so easy to view the database, if only to view the database and then put the phone root, a little more than the loss, So the following will provide a way to view the database without
