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 t

is not an arrayTo enable chained queries that support query results, realm customizes a collection type. Can enumerate, but is not familiar with the array anymore. Because of the lazy loading mechanism of realm, it is not recommended to turn this enumeration into an array type at the data layer. The disadvantage is that the upper layer knows the storage logic of the data. Strictly speaking, we should not let the upper level know. But this design may be to facilitate the retrieval of the upper l

. (rounded).OK, the design of the database is this way, to finish this feeling in fact the design of the database is not difficult, as long as they can analyze the focus of what is done in the good.The app's core data is actually a record, which includes category, time, time, and so on field values.However, it is not possible to design only one table, because designing a table is not conducive to querying a

One. Use the ADB command to viewOpen a command window and go to Platform-tools in the Android SDK directory to execute the command:1. Input: Under Windows: adb shell under Linux: ./adb Shell2. Enter Data/data: If the phone does not have root, use the command Run-as package name to go directly to/data/data3. Go to databases: CD databases4. Use the ls command to list all databases in the current directory5. Use the sqlite3

When the application version upgrade to do some sqlit operation, such as adding a field, then the version upgrade after the Sqlit does not update will inevitably errorThen Sqlit provides the alert Table command, which allows the user to rename or add fields to the tableSpecific solutions (take the table to add fields as an example):1. Change table name A to temporary table temp_a: NBSP; 2. Create a new table A with the same original indication (the field in the new table has been incremented) N

1. Preface Idle to be bored. The phone is something that comes into contact every day. What is the easiest way to get in touch with a program? Think of some people saying that both front and back are all stacks. Oh, look at the HTML5 full stack. I'd say it's interesting to have more contact. Write back end every day. It's not a business layer. It's not a big algorithm. The front end is much more interesting. Of course, I'm the old one. It's not ag.vue,react. It's just that the water in the fron

Objective As Android developers, presumably more or less to touch the start speed optimization related things, when the user more and more, the product function with more and more iterations, the App gradually become bloated is a very common phenomenon, even can be said to be unavoidable phenomenon, followed by the work is to optimize the performance of the app,

, which may be more comprehensive and efficient than managing images by ourselves. I will recommend the following image management libraries: (1) Some official Google Apps, such as Google photos, use Glide. Do you want to explain more? (2) Fresco, FaceBook's open-source Library, is extremely powerful and supports WebP, Gif, and JPEG progressive display. The key is its design philosophy on image memory, which greatly reduces the image memory overhead. (3) And
