3. When your application is updated…
4. You may… • Change database scheme • Write new preferences • Migrate to new data models • Trigger data synchronization • and so on…
5. It could happen! int current = // get current version code from PackageManager int previous = // read previous version from Preference if (current <= previous) { return; } if (previous < 1) {} // do when the app is updated from 0 if (previous < 2) {} // do when the app is updated from 0 or 1 if (previous < 3) {} // do when the app is updated from 0 ~ 2 if (previous < 4) {} if (previous < 5) {} if (previous < 6) {}
6. It could happen! int current = // get current version code from PackageManager int previous = // read previous version from Preference if (current <= previous) { return; } if (previous < 1) {} // do when the app is updated from 0 if (previous < 2) {} // do when the app is updated from 0 or 1 if (previous < 3) {} // do when the app is updated from 0 ~ 2 if (previous < 4) {} if (previous < 5) {} if (previous < 6) {}
7. Too many “if” statement! int current = // get current version code from PackageManager int previous = // read previous version from Preference if (current <= previous) { return; } if (previous < 1) {} // do when the app is updated from 0 if (previous < 2) {} // do when the app is updated from 0 or 1 if (previous < 3) {} // do when the app is updated from 0 ~ 2 if (previous < 4) {} if (previous < 5) {} if (previous < 6) {}
8. Just fit for you https://github.com/KeithYokoma/Fit
9. Fit • Annotation based • Automatically call your procedure • Reusable method declaration • No more dull “if” statement
10. Version Module class public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
11. Version Module class public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
12. Version Module class public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
13. Application class public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); Fit.initialize(this, new MyModule()); Fit.getInstance().execute(); } }
14. Application class public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); Fit.initialize(this, new MyModule()); Fit.getInstance().execute(); } }
15. Application class public class MyApplication extends Application { @Override public void onCreate() { super.onCreate(); Fit.initialize(this, new MyModule()); Fit.getInstance().execute(); } }
16. That’s it!
17. Behaviour Version 1 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
18. Behaviour Version 1 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
19. Behaviour Version 1 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
20. Behaviour Version 1 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
21. Behaviour Version 1 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
22. Behaviour Version 3 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
23. Behaviour Version 3 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
24. Behaviour Version 3 to 4 public class MyModule implements VersionModule { // foo() is called when the app is updated to // version code = 1, 2 and 3 @VersionCode({1, 2, 3}) public void foo() {} // bar() is called when the app is updated to version code = 4 @VersionCode(4) public void bar() {} }
