StrictMode.ThreadPolicy.Builder

Kotlin |Java

public static final class StrictMode.ThreadPolicy.Builder
extends Object

java.lang.Object
↳	android.os.StrictMode.ThreadPolicy.Builder

Creates ThreadPolicy instances. Methods whose names start with detect specify what problems we should look for. Methods whose names start with penalty specify what we should do when we detect a problem.

You can call as many detect and penalty methods as you like. Currently order is insignificant: all penalties apply to all detected problems.

For example, detect everything and log anything that's found:

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
     .detectAll()
     .penaltyLog()
     .build();
 StrictMode.setThreadPolicy(policy);

Public constructors

StrictMode.ThreadPolicy.Builder

Added in API level 9

public StrictMode.ThreadPolicy.Builder ()

Create a Builder that detects nothing and has no violations. (but note that build() will default to enabling penaltyLog() if no other penalties are specified)

StrictMode.ThreadPolicy.Builder

Added in API level 9

public StrictMode.ThreadPolicy.Builder (StrictMode.ThreadPolicy policy)

Initialize a Builder from an existing ThreadPolicy.

Parameters
`policy`	`StrictMode.ThreadPolicy`

Public methods

build

Added in API level 9

public StrictMode.ThreadPolicy build ()

Construct the ThreadPolicy instance.

Note: if no penalties are enabled before calling build, penaltyLog() is implicitly set.

Returns
`StrictMode.ThreadPolicy`

detectAll

Added in API level 9

public StrictMode.ThreadPolicy.Builder detectAll ()

Detect everything that's potentially suspect.

As of the Gingerbread release this includes network and disk operations but will likely expand in future releases.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectCustomSlowCalls

Added in API level 11

public StrictMode.ThreadPolicy.Builder detectCustomSlowCalls ()

Enable detection of slow calls.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectDiskReads

Added in API level 9

public StrictMode.ThreadPolicy.Builder detectDiskReads ()

Enable detection of disk reads.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectDiskWrites

Added in API level 9

public StrictMode.ThreadPolicy.Builder detectDiskWrites ()

Enable detection of disk writes.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectNetwork

Added in API level 9

public StrictMode.ThreadPolicy.Builder detectNetwork ()

Enable detection of network operations.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectResourceMismatches

Added in API level 23

public StrictMode.ThreadPolicy.Builder detectResourceMismatches ()

Enables detection of mismatches between defined resource types and getter calls.

This helps detect accidental type mismatches and potentially expensive type conversions when obtaining typed resources.

For example, a strict mode violation would be thrown when calling TypedArray.getInt(int, int) on an index that contains a String-type resource. If the string value can be parsed as an integer, this method call will return a value without crashing; however, the developer should format the resource as an integer to avoid unnecessary type conversion.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

detectUnbufferedIo

Added in API level 26

public StrictMode.ThreadPolicy.Builder detectUnbufferedIo ()

Detect unbuffered input/output operations.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyDeath

Added in API level 9

public StrictMode.ThreadPolicy.Builder penaltyDeath ()

Crash the whole process on violation. This penalty runs at the end of all enabled penalties so you'll still get see logging or other violations before the process dies.

Unlike penaltyDeathOnNetwork(), this applies to disk reads, disk writes, and network usage if their corresponding detect flags are set.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyDeathOnNetwork

Added in API level 11

public StrictMode.ThreadPolicy.Builder penaltyDeathOnNetwork ()

Crash the whole process on any network usage. Unlike penaltyDeath(), this penalty runs before anything else. You must still have called detectNetwork() to enable this.

In the Honeycomb or later SDKs, this is on by default.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyDialog

Added in API level 9

public StrictMode.ThreadPolicy.Builder penaltyDialog ()

Show an annoying dialog to the developer on detected violations, rate-limited to be only a little annoying.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyDropBox

Added in API level 9

public StrictMode.ThreadPolicy.Builder penaltyDropBox ()

Enable detected violations log a stacktrace and timing data to the DropBox on policy violation. Intended mostly for platform integrators doing beta user field data collection.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyFlashScreen

Added in API level 11

public StrictMode.ThreadPolicy.Builder penaltyFlashScreen ()

Flash the screen during a violation.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyListener

Added in API level 28

public StrictMode.ThreadPolicy.Builder penaltyListener (Executor executor, 
                StrictMode.OnThreadViolationListener listener)

Call #OnThreadViolationListener#onThreadViolation(Violation) on specified executor every violation.

Parameters
`executor`	`Executor`: This value must never be `null`.
`listener`	`StrictMode.OnThreadViolationListener`: This value must never be `null`.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.

penaltyLog

Added in API level 9

public StrictMode.ThreadPolicy.Builder penaltyLog ()

Log detected violations to the system log.

Returns
`StrictMode.ThreadPolicy.Builder`	This value will never be `null`.
