How To Clear Android Internal Storage

You may need to move your fingers around slightly up or down until you feel the pulsing. Use a watch with a second hand, or look at a clock with a second hand. Count the beats you feel for 10 seconds. Multiply this number by six to get your heart rate (pulse) per minute. If you’re sitting or lying and you’re calm, relaxed and aren’t ill, your heart rate is normally between 60 (beats per minute) and 100 (beats per minute). But a heart rate lower than 60 doesn’t necessarily signal a medical problem. It could be the result of taking a drug such as a beta blocker. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. Tachycardia is a high heart rate, defined as above 100 bpm at rest. Bradycardia is a low heart rate, defined as below 60 bpm at rest. During sleep a slow heartbeat with rates around 40–50 bpm is common and is considered normal. A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. To measure your heart rate, simply check your pulse. Your pulse rate is the number of times your heart beats per minute. A normal resting heart rate should be 60–100 beats per minute, but it can vary from minute to minute. It can go up to 130–150 beats or higher per minute when you’re exercising – that’s normal because the body needs to pump more oxygen-rich blood around the body. Rapid heart rate could be due to a range of conditions. How many times does a human heart beat per minute.

1 What Is Android Internal Storage

Clear Storage Space on Android Phone For the proper functioning of your device, it is necessary that you get into the habit of clearing storage space on your Android Phone or Table. This can be done by periodically removing unwanted Photos, Videos, Documents and other files from your Android Phone. Now, most Android smartphones allow users to augment their storage capacity using an external memory card or SD card. There is a dedicated SD card slot where you can insert a memory card and transfer some of your data to free up space on your internal storage. Better solution: get more space for the internal memory. When the Android space is running out, you can use the above methods to free up space without deleting apps, or you can also try to increase internal memory storage of Android. That is to say, add a MicroSD card to your Android device and move some apps or large files to the SD card.

Android allows your android application save or cache private data or files on the device memory, which is called internal storage.

Data saved or cached in internal storage are private and can be accessed only within your application, other applications cannot access them.

Furthermore, data of your application that is saved in internal storage will be also deleted if user remove your application.

2 APIs

The absolute path of internal storage folder is: /data/data/<YOUR_APP_PACKAGE_NAME>/files/. Call getFilesDir() method to obtain this path. getFilesDir() will return a java.io.File object. Then you can simply use java IO APIs to read or write files under internal storage folder.

2.1 Write

We will create a simple demo application to write a file to internal storage.

Main UI controls here:

A Button, click to write file;
Another Button, click to read saved file;
A TextView to display the absolute file path of internal storage;

The file to be saved named hello.txt, and we'll write a string 'Hello World!' to it. Make something good today.

2.2 Read

Reading file from internal storage is also simple, just like the common Java IO operations.

We'll add a read button in above demo application. After clicking read button, a popup Toast will display the content read from internal storage file.

2.3 Cache

Instead of getFilesDir(), getCacheDir() will return an internal storage folder path for caching data. The absolute path returned by getCacheDir() is: /data/data/<YOUR_APP_PACKAGE_NAME>/cache/. This folder is used to cache some temporary files in your application.

There are important differences between files folder and cache folder in internal storage.

The data saved under cache folder will be deleted automatically by Android system if the spare space of internal storage is not enough or full;
The data saved under files folder will NOT be deleted unless device user clear it explicitly.

Android provided UI interface to clear cache or data of an installed application. In your Android device or emulator, navigate to Settings > Apps > YOUR_APP > storage you can see two clear buttons.

Clear Cache: will delete all data under /data/data/<YOUR_APP_PACKAGE_NAME>/cache/;
Clear Data: will delete all custom data under your application folder, including BOTH/data/data/<YOUR_APP_PACKAGE_NAME>/cache/AND/data/data/<YOUR_APP_PACKAGE_NAME>/files/;

It is a best practice to save the important data of your application into the path that is returned by getFilesDir().

For many Android users, one of the worst problems they face is the low storage issue. If you're facing this issue: 'Error: not enough memory on your mobile device', you're not alone. In this article, we'll discuss how to clean phone memory to free up space on Android.

There are two types of phones that come in handling the storage area. One is phones with both internal storage and sd card support. Another is phones with only internal storage.

If your phone supports sd card, it is easy to move photos, videos, and other files from internal to external memory.
