清理缓存

Posted 2022-11-24 zero-27

1.清理单个缓存

//系统设置界面
								Intent intent = new Intent(
										"android.settings.APPLICATION_DETAILS_SETTINGS");
								intent.setData(Uri.parse("package:"
										+ packageName));
								startActivity(intent);

2.清理所有缓存,需要aidl文件

public void clearAll() 
		try 
			// 反射
			Class type = PackageManager.class;
			Method method = type.getDeclaredMethod("freeStorageAndNotify",
					long.class, IPackageDataObserver.class);
			// 接口回调
			IPackageDataObserver mObserver = new IPackageDataObserver.Stub() 

				@Override
				public void onRemoveCompleted(String packageName,
						boolean succeeded) throws RemoteException 
					mHandler.obtainMessage(CLEARFINISH).sendToTarget();
				

			;
			// 方法调用
			method.invoke(mPm, Integer.MAX_VALUE, mObserver);
		 catch (Exception e) 
			e.printStackTrace();
