android-2.2-froyo

I have a need to use ParcelFileDescriptor.createPipe() , but I would still like to target API 8/Froyo. This function requires API 9/Gingerbread. I have read that there are compatibility kits that allow newer API functions to be used on the older OS versions, but know nothing about them. Is that an option here? If not, what would be the cleanest method for going about duplicating this functionality? I have considered using fromSocket() and making a simple network connection over the loopback interface, but that seems like more overhead than is needed, if there were a simpler way. Any thoughts

I was writing an Android app for Android SDK 2.3.3 but then I was asked to test it on a device running Android 2.2.1. So I set my target to 8 instead of 10. But then java.util.concurrent.TimeUnit only had the Java 1.5 feature set instead of the Java 1.6/1.7 feature set of java.util.concurrent.TimeUnit. So I put the openjdk 6 implementation of TimeUnit into my package for my Android app and everything works fine. Does anyone know where I can get some documentation that gives me a chart that tells me, for example, that when using the official SDK, Android 2.2 has to be coded using Java 1.5

I noticed the default camera activity I call on a Droid X is different looking than the one on my Droid and Nexus One. After selecting "OK" on the Droid and Nexus One, the activity would finish - the Droid X has a "Done" button (which takes you back to the Camera, instead of finishing the activity), and the only way to get to the screen I want is to hit the "Back" button. Here is the class that works on Android 2.2/2.3, but not for Droid X's: package com.android.xxx; import java.io.File; import android.content.Intent; import android.net.Uri; import android.os.Bundle; import android.os

When I try opening eclipse it opens, but it shows one error i.e Android SDK content Loader has encountered a problem.parseSdkContent failed When I click on details button, it shows me parseSdkContent failed java.lang.NullPointeException . And when I tried to create AVD it shows error that Location of the android SDK has not been setup in the preferences while I have already set the path in preferences. Please help me. Because of this issue my work is pending. I work in this problem for 2 days. In my workspace I have 2 projects. After review both project.properties, project 1 reference project

Some Android 2.x tablets such as the HTC Flyer and Samsung Galaxy Tab support both internal tablet storage and an external SD card. For example on my Flyer, /sdcard and /sdcard2 are separate, with the former representing the tablet's "internal storage." If I use Environment.getExternalStorageDirectory() , there doesn't seem to be any set rule on which of those storage locations will be returned. In using getExternalStorageDirectory() , my concern is that I'll only find media stored on one of the two storage locations. One solution is to just hard-code scanning /sdcard* into the application,

I'm not very clear about the Intent object and how to use it to pass data between Activities. In my application I have several tabs between which I want to pass ArrayList. Here is a sample code I plan to use, but I'm missing the part where the main activity catches the Intent and passes it to the new activity on start : 1. myTabs.java ==> This is where I think I need to add some code to pass the data between TabOne and TabTwo. For now it is just using the sample code of the TabActivity sample. public class myTabs extends TabActivity { /** Called when the activity is first created. */ @Override

Im trying to build an app which tries to auto focus the camera before starting the video recording. Directly using MediaRecorder does not auto focus the camera. For that i am Using Camera and using the callback I can autofocus it. But providing this instance to the MediaRecorder gives me a lot of issues. Following is the code im using for recording public boolean startRecording() { try { mCamera.unlock(); mediaRecorder = new MediaRecorder(); mediaRecorder.setCamera(mCamera); mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC); mediaRecorder.setVideoSource(MediaRecorder.VideoSource
