Your app must register each fence before it can be used.\n\nRegister a fence\n----------------\n\nTo register a fence, use the\n[`FenceClient`](/android/reference/com/google/android/gms/awareness/FenceClient),\nand to construct a [`FenceUpdateRequest`](/android/reference/com/google/android/gms/awareness/FenceClient#updateFences(com.google.android.gms.awareness.fence.FenceUpdateRequest)),\nuse [`FenceClient.updateFences()`](/android/reference/com/google/android/gms/awareness/FenceClient#updateFences(com.google.android.gms.awareness.fence.FenceUpdateRequest)).\nCall `addFence()` for each fence to add.\n\nThe following are required to register, and unregister, a fence:\n\n- A [Google Play Services API Client](/awareness/android-api/get-started#import_awareness_api_dependencies) instance.\n- An `AwarenessFence` instance, which is the fence itself.\n- A `PendingIntent` to handle state changes.\n- A fence key, which is a string that identifies the fence and maps to an `AwarenessFence`-`PendingIntent` pair.\n\nThe following code example shows a method that calls `updateFences()` to\nregister a fence: \n\n Awareness.getFenceClient(this).updateFences(new FenceUpdateRequest.Builder()\n .addFence(FENCE_KEY, exercisingWithHeadphonesFence, mPendingIntent)\n .build())\n .addOnSuccessListener(new OnSuccessListener\u003cVoid\u003e() {\n @Override\n public void onSuccess(Void aVoid) {\n Log.i(TAG, \"Fence was successfully registered.\");\n }\n })\n .addOnFailureListener(new OnFailureListener() {\n @Override\n public void onFailure(@NonNull Exception e) {\n Log.e(TAG, \"Fence could not be registered: \" + e);\n }\n });\n\nTo create multiple fences with unique fence keys, call `addFence()`\nmultiple times. You can use as many `PendingIntent` methods as you need to, but it's\npreferable to use a single `PendingIntent` for all fence callbacks. If you\nuse a fence key that has already been registered to call `addFence()`, the\n`AwarenessFence` and `PendingIntent` values are overwritten for that key.\n\nUnregister a fence\n------------------\n\nTo unregister a fence, call\n[`getFenceClient().updateFences()`](/android/reference/com/google/android/gms/awareness/Awareness#getFenceClient(android.app.Activity)),\nand use [`FenceUpdateRequest.Builder()`](/android/reference/com/google/android/gms/awareness/fence/FenceUpdateRequest.Builder)\nto construct a fence update request. Then call `removeFence()`, as the\nfollowing example shows: \n\n Awareness.getFenceClient(this).updateFences(new FenceUpdateRequest.Builder()\n .removeFence(FENCE_KEY)\n .build())\n .addOnSuccessListener(new OnSuccessListener\u003cVoid\u003e() {\n @Override\n public void onSuccess(Void aVoid) {\n Log.i(TAG, \"Fence was successfully unregistered.\");\n }\n })\n .addOnFailureListener(new OnFailureListener() {\n @Override\n public void onFailure(@NonNull Exception e) {\n Log.e(TAG, \"Fence could not be unregistered: \" + e);\n }\n });\n\n| **Note:** You can add and remove fences in the same `FenceUpdateRequest`. Additions and removals are performed in the same order that `addFence()` and `removeFence()` are called in the request.\n\nNext step: [Manage fence callbacks](/awareness/android-api/fence-callbacks)."]]
