APP_DATA_TYPE_FILE_TYPE_APK

 public static final int APP_DATA_TYPE_FILE_TYPE_APK

Represents all .apk files in application code path. Can be used as an input to getAppBytesByDataType(int) to get the sum of sizes for files of this type.

Constant Value: 3 (0x00000003)

APP_DATA_TYPE_FILE_TYPE_CURRENT_PROFILE

 public static final int APP_DATA_TYPE_FILE_TYPE_CURRENT_PROFILE

Represents current profile of application. Current profiles may or may not be used during the next profile-guided dexopt. Can be used as an input to getAppBytesByDataType(int) to get the size of files of this type. This size fluctuates regularly, it goes up when the user uses more and more classes/methods and comes down when a deamon merges this into the ref profile and does profile-guided dexopt.

Constant Value: 2 (0x00000002)

APP_DATA_TYPE_FILE_TYPE_DEXOPT_ARTIFACT

 public static final int APP_DATA_TYPE_FILE_TYPE_DEXOPT_ARTIFACT

Represents all nonstale dexopt and runtime artifacts of application. This includes AOT-compiled code and other data that can speed up app execution. For more detailed information, read the JIT compiler guide. Dexopt artifacts become stale when one of their dependencies has changed. They may be cleaned up or replaced by ART Services at any time. For a preload app, this type includes dexopt artifacts on readonly partitions if they are up-to-date. Can be used as an input to getAppBytesByDataType(int) to get the sum of sizes for files of this type. The sum might include the size of data that is part of appBytes, dataBytes or cacheBytes.

Constant Value: 0 (0x00000000)

APP_DATA_TYPE_FILE_TYPE_DM

 public static final int APP_DATA_TYPE_FILE_TYPE_DM

Represents all .dm files in application code path. Can be used as an input to getAppBytesByDataType(int) to get the sum of sizes for files of this type.

Constant Value: 4 (0x00000004)

APP_DATA_TYPE_FILE_TYPE_REFERENCE_PROFILE

 public static final int APP_DATA_TYPE_FILE_TYPE_REFERENCE_PROFILE

Represents reference profile of application. Reference profiles are the ones used during the last profile-guided dexopt. If the last dexopt wasn't profile-guided, then these profiles were not used. Can be used as an input to getAppBytesByDataType(int) to get the size of files of this type.

Constant Value: 1 (0x00000001)

APP_DATA_TYPE_LIB

 public static final int APP_DATA_TYPE_LIB

Represents lib/ in application code path. Can be used as an input to getAppBytesByDataType(int) to get the size of lib/ directory.

Constant Value: 5 (0x00000005)

CREATOR

 public static final Creator<StorageStats> CREATOR

describeContents

 public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

getAppBytes

 public long getAppBytes ()

Return the size of app. This includes APK files, optimized compiler output, and unpacked native libraries.

If the primary external/shared storage is hosted on this storage device, then this includes files stored under Context.getObbDir().

Code is shared between all users on a multiuser device.
Value is a non-negative number of bytes.

getAppBytesByDataType

 public long getAppBytesByDataType (int dataType)

Return the size of the specified data type. This includes files stored under application code path.

If there is more than one package inside a uid, the return represents the aggregated stats when query StorageStat for package or uid. The data is not collected and the return defaults to 0 when query StorageStats for user.

Data is isolated for each user on a multiuser device.

getCacheBytes

 public long getCacheBytes ()

Return the size of all cached data. This includes files stored under Context.getCacheDir() and Context.getCodeCacheDir().

If the primary external/shared storage is hosted on this storage device, then this includes files stored under Context.getExternalCacheDir().

Cached data is isolated for each user on a multiuser device.
Value is a non-negative number of bytes.

getDataBytes

 public long getDataBytes ()

Return the size of all data. This includes files stored under Context.getDataDir(), Context.getCacheDir(), Context.getCodeCacheDir().

If the primary external/shared storage is hosted on this storage device, then this includes files stored under Context.getExternalFilesDir(String), Context.getExternalCacheDir(), and Context.getExternalMediaDirs().

Data is isolated for each user on a multiuser device.
Value is a non-negative number of bytes.

getExternalCacheBytes

 public long getExternalCacheBytes ()

Return the size of all cached data in the primary external/shared storage. This includes files stored under Context.getExternalCacheDir().

Cached data is isolated for each user on a multiuser device.
Value is a non-negative number of bytes.

writeToParcel

 public void writeToParcel (Parcel dest, int flags)

Flatten this object in to a Parcel.
