Builder

class Builder
kotlin.Any
   ↳ 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

Builder

Added in API level 9
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)

Builder

Added in API level 9
Builder(policy: StrictMode.ThreadPolicy!)

Initialize a Builder from an existing ThreadPolicy.

Public methods

build

Added in API level 9
fun build(): StrictMode.ThreadPolicy!

Construct the ThreadPolicy instance.

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

detectAll

Added in API level 9
fun detectAll(): StrictMode.ThreadPolicy.Builder

Detect everything that's potentially suspect.

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

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectCustomSlowCalls

Added in API level 11
fun detectCustomSlowCalls(): StrictMode.ThreadPolicy.Builder

Enable detection of slow calls.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectDiskReads

Added in API level 9
fun detectDiskReads(): StrictMode.ThreadPolicy.Builder

Enable detection of disk reads.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectDiskWrites

Added in API level 9
fun detectDiskWrites(): StrictMode.ThreadPolicy.Builder

Enable detection of disk writes.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectExplicitGc

Added in API level 34
fun detectExplicitGc(): StrictMode.ThreadPolicy.Builder

Detect calls to Runtime#gc().

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectNetwork

Added in API level 9
fun detectNetwork(): StrictMode.ThreadPolicy.Builder

Enable detection of network operations.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectResourceMismatches

Added in API level 23
fun detectResourceMismatches(): StrictMode.ThreadPolicy.Builder

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 android.content.res.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.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

detectUnbufferedIo

Added in API level 26
fun detectUnbufferedIo(): StrictMode.ThreadPolicy.Builder

Detect unbuffered input/output operations.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyDeath

Added in API level 9
fun penaltyDeath(): StrictMode.ThreadPolicy.Builder

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.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyDeathOnNetwork

Added in API level 11
fun penaltyDeathOnNetwork(): StrictMode.ThreadPolicy.Builder

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.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyDialog

Added in API level 9
fun penaltyDialog(): StrictMode.ThreadPolicy.Builder

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

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyDropBox

Added in API level 9
fun penaltyDropBox(): StrictMode.ThreadPolicy.Builder

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

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyFlashScreen

Added in API level 11
fun penaltyFlashScreen(): StrictMode.ThreadPolicy.Builder

Flash the screen during a violation.

Return
StrictMode.ThreadPolicy.Builder This value cannot be null.

penaltyListener

Added in API level 28
fun penaltyListener(
    executor: Executor,
    listener: StrictMode.OnThreadViolationListener
): StrictMode.ThreadPolicy.Builder

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