Android Toolsを21.1にアップグレードしてから、この問題が発生しています。クリーンなワークスペースでもEclipseを開始すると、エラーが発生parseSdkContent failedし、詳細は次のようになります。
com.android.sdklib.devices.DeviceManager.createInstance
(Ljava/lang/String;Lcom/android/utils/ILogger;)
Lcom/android/sdklib/devices/DeviceManager;
私はインターネットを検索し、ほとんどすべての解決策を試しましたが、役に立ちませんでした。Androidの設定に移動し、SDKへのパスを設定しようとすると、使用可能なターゲットがないと表示されます。他に試すことができるものはありますか？修正されるまで、Android開発を行うことはできません。
Step 1. Find the folder named: .android
This folder can be located in your Windows user directory, for example in Windows 7 or 8:
C:\Users\YOUR_WINDOWS_USERNAME\.android
Step 2. Delete this folder .android
Step 3. Restart Eclipse and your problem will be solved.
You DON'T have to delete ANYTHING
For me updating the DDMS from ADT plugin did the trick!
Before that, to save time I only updated ADT plugin, nothing else like Android DDMS, TraceView etc., so I ran into same issue.
After a couple of restarts and Google searches everyone was proposing different solutions. I updated my Android DDMS and restarted eclipse and it worked like a charm!
I didn't have to remove my workspace or update my .project file etc.
Ok I just deleted eclipse and reinstalled. Lost all of my settings etc. but it's all I could do. Something must have gotten corrupted in the upgrade of the ADT.
I had the same issue after installing 21.1 on a new machine. Solved it by deleting the default workspace I created during the first launch and then re-starting ADT as Administrator, recreating the workspace. After closing and re-running it as a normal user the problem disappeared.
Re-installing the new version of ADT (which at the time is ADT-23.0.3.zip(http://developer.android.com/sdk/installing/installing-adt.html)) helped me with the same problem you are described above. This message may be a little to late but hope this can also help others.
Uninstalling API 21 and installing API 19 worked for me.
In Eclipse, use the Check For Updates item in the Help menu to update the Eclipse-part of your Android tools (called ADT).
Try to go to your eclipse workspace and delete the .meta folder.
I was recently having the same problem and i figured it out that one must install/update other necessary software related to ADT.Suppose you are updating your ADT then you must also update DDMS with it.So,best option is to install the all software/plugin pack for the version you are updating.
When you uninstall the full thing and install it again,all of these related software get installed in same version so it always solves the problem.
According to me re installing should be final solution.
I got mine fixed by, before restarting your IDE, make your activity main layout as the current tab open, then restart your IDE. Hope it helps :)
This did it for me.
In Eclipse go to
Project Properties -> Java Compiler and set 'Compiler Compliance Level' to 1.7
For me I delete Android 5(API 21) installed software packages from SDK manager. I am working on API 20 ( Android 4.4w.2). It only solved my problem completely. Delete .android folder or others didnt help me out.
Deleting ".android" is temporarily fixing the problem with me as after sometime it begins to come again ..
Here is another cause and fix that might help .. This is happening because of existence of 2 versions of SDK in the same machine but in case you have only one version (probably it is 21) just download the SDK platform for API 20 (4.4W) as there is a problem in 21's "layoutlib.jar"). start applying the following:
Close Eclipse
Navigate to your sdk folder (something like C:\adt-bundle-windows-x86_64-20140321\sdk)
Go to platforms folder -> android-21 folder -> data folder and rename layoutlib.jar (for backup only)
Copy the same file (layoutlib.jar) from your android-20 folder to this folder "android-21"
Start Eclipse
maybe you have more than one android IDE installed, for example ,you installed android studio and adt+ eclipse all,just remove one can fix this problem
