Sending data back and forth between two Activities in Android


Tag : java , By : Allen

Hope this helps You need to start B with startActivityForResult() and override onActvityResult() in A. Before you finish B you will need to call setResult() to set the data you want to send back to A.
Read the section of Starting Activities in the documentation.

Android:Sending data periodically

around this issue I'm pretty sure you can set the sensitivity of the sensor, or min change before the listener is called again (a bit like with finding your location).
If that fails, you can always put in a little check yourself based on the info to change a min amount, or using the System time to calculate a difference with the last time you allowed it to write data, and check that for whatever time you want as delay.

hop of those help? If you find yourself needing to maintain quite a lot of the same information across activities, you can also use the Application class to store global state variables.

Most secure way of sending data between activities in Android

fixed the issue. Will look into that further Putting the data in the Intent would be the least secure, insofar as that data is being sent by IPC from your process to a core OS process, then back to your process via another IPC invocation. On modern versions of Android, I know of no security issues with this — other apps cannot spy on that IPC or otherwise get at that data. However, all else being equal, keeping the sensitive data within your process at all times would be more secure than passing that data outside of your process.
The cited "Persist objects (sqlite, share preferences, file, etc.)" is not a way of passing data between components. It is a way of persisting data for long-term use. Now, most apps need such persistence, and so you may have persistence for other reasons and simply leverage it (e.g., A triggers writing data; E reads in that data). From an efficiency standpoint, though, disk I/O is slow, and so you do it when you need persistence, not data passing. Typically, though, with persistence, we maintain some sort of in-memory cache, to minimize that disk I/O. That involves static fields and WeakReferences, the other option cited in that Stack Overflow answer.
